UMZEKELO hlula inani ngenani. ngokucandeka Table

Nangona isibakala sokuba abantu abaninzi bacinga izibalo bhaza wenzululwazi, oko akunjalo. imisebenzi emininzi lwezibalo kulula kakhulu ukuba baqonde, ingakumbi ukuba uyayazi imigaqo kunye neefomula. Ngoko ke, ukwazi iitafile phindo, ungenza ngokukhawuleza nande engqondweni amanani amakhulu. Eyona nto ibalulekileyo - baqeqeshwe rhoqo kwaye ukuba ukulibala imigaqo-phindo. Kukwanjalo ke ngecandelo.

Makhe sihlaziye ukwahlulwa amanani apheleleyo, amaqhezu kunye navumelanayo. Makhe ukukhumbula imigaqo esisiseko, ubuchule kunye nendlela.

ukwahlukana operation

Masiqalise ngokucacisa igama kunye nenombolo, ukuba nenxaxheba kulo msebenzi. Oku kuya kulungiselela kakhulu ulwazi ntetho vetshe kunye ziqhele.

Division - enye imisebenzi ezine ezisisiseko zemathematika. isifundo yayo iqala esikolweni aphantsi. Loko abantwana zibonisa umzekelo wokuqala ngokwahlula inani ngenani, chaza imithetho.

Umsebenzi ababandakanyekayo amanani amabini, kwisahlulo, umahluli. Lokuqala - inani elo wahlulelene, kwaye eyesibini - apho isabelo. Ngenxa yoko QUOTIENT sisahlula.

Kukho notation eziliqela ekulobeni izivumelwano, ":", "/" kunye umgca oxwesileyo - ukurekhoda ngesekhondi apho tivi na phezulu nasezantsi, ngezantsi umgca - ehlukanisayo.

imithetho

Xa ukuhlola umsebenzi othile zezibalo ufuna utitshala ukuba balandele abafundi kunye nemigaqo esisiseko ukuba ufanele ukwazi. Noko ke, azisoloko sakhunjulwa njengoko kulungileyo, njengoko sithanda. Kungenxa yoko le nto siye sagqiba ukuhlaziya inkumbulo lwakho imithetho emine esisiseko.

Imithetho ezisisiseko ukwahlulwa amanani kufuneka ukuba ukhumbule:

1. Yabelana ku zero akakwazi. Umthetho ukukhumbula kwindawo yokuqala.

2. Yabelana a zero lingaba naliphi na inani, kodwa ekugqibeleni iya kusoloko zero.

3. Ukuba inombolo wahlulwe ngabanye, siya kufumana inani elifanayo.

4. Ukuba inani wahlulwe ngokwawo, siya kufumana enye.

Njengoko ubona, imigaqo elandelwayo kakhulu ilula kwaye kulula ukuba ukukhumbula. Nangona abanye abantu usenokulibala ulawulo ezilula ezifana nokungakwazi ukuba zahlule ngu zero, okanye ukudida nabo kwisahlulo ngenani zero.

Iimpawu ze divisibility ye inani

Enye imithetho kakhulu luncedo - uphawu apho umiselwa ithuba ngokwahlula inani zendalo ukuya kwenye ngaphandle abaseleyo. Ngenxa yoko, iimpawu angawodwa divisibility-2, 3, 5, 6, 9, 10. Cinga nenkcazelo eneenkcukacha ngezantsi. Bona lula kakhulu ukuphunyezwa imisebenzi amanani. Kwakhona khona umzekelo ngamnye ulawulo kwisahlulo inani.

Ezi jikelele-iimpawu ezisetyenziswa yi zezibalo.

divisibility uphawu 2

I ilula ukukhumbula umqondiso. Inani apho iphela ngesifundo inani (2, 4, 6, 8) okanye 0 zisoloko ngokulinganayo ziyahluleka ngo ezimbini. Bekulula ukukhumbula nokusebenzisa. Ngenxa yoko, inani 236 uphela an inani, yaye ngoko, yahlulwe kabini ngokulinganayo.

Kungenwe: 236 2 = 118. Eneneni, 236 umahlule ngo-2 ngaphandle nentsalela.

Lo mthetho lo waziwa kakhulu kakuhle, nje abadala kodwa abantwana.

divisibility uphawu 3

Indlela ukuze enze icandelo inombolo 3? Khumbula umthetho elandelayo.

A inani liyohluleka ngo-3 ngokulinganayo xa kuthe isixa lamasuntswana yayo liyohluleka ngo ezintathu. Ngokomzekelo, cinga inani 381. Le udibaniso lwamaxabiso wonke amanani ziya 12. Eli nani okanye iphinda amathathu, kwaye hlulwa nge-3 ngaphandle nentsalela.

Kwakhona khangela phandle lo mzekelo. 381: 3 = 127, koko konke kulungile.

Uphawu divisibility of integers 5

Kukho kwakhona zilula. Yahlula zibe 5 ngaphandle kwintsalela nga kuphela ezo amanani anesandi kwi-5 okanye 0. Ngokomzekelo, cinga inani ezifana 705 okanye 800. Isiphelo yokuqala 5, okwesibini - kunothi, ngoko ke bobabini ziyahluleka ngo 5. Le ukusuka kulawulo elula ekuvumela ukuba ukwahlula ngokukhawuleza ngenani elinemivo 5.

Ukuze uqinisekise ukuba umqondiso Imizekelo: 405: 5 = 81; 600: 5 = 120. Njengoko ubona, uphawu isebenza.

Liyohluleka ngo 6

Ukuba ufuna ukwazi ukuba inombolo 6, kuqala uza kufuneka ufumanise ukuba liyohluleka ngo-2, uze emva koko wahlulelana - ngo 3. Ukuba kunjalo, ngoko ke inani nabanako ukwahlulelana ngaphandle intsalela ngu 6. Hi xikombiso, inani 216 ngo-2 njengemfezeko an inani, no-3, njengoko inani lamasuntswana ngu-9.

Qinisekisa: 216: 6 = 36 Lo mzekelo ubonisa ukuba oku izenzo isici.

Liyohluleka ngo 9

Kwakhona uthethe ukuphumeza indlela amanani ukwahlula 9. Ngelo lenani elinikiweyo yahlukana ezo amanani zendalo, isixa yayo umgaqo nemivo ezininzi 9. Ngokufanayo ifan'ba 3. Umzekelo, inani 918. Ukubeka onke amanani kwaye ufumane 18 - multiple-9. Ngoko ke, yahlulelwe kwii-9 ngaphandle, azafunyanelwa ndawo.

Thina ukusombulula lo mzekelo vavanyo: 918: 9 = 102.

Severability 10

Eyona nkalo yokugqibela, nto leyo ukuyazi. 10 zahlulwe kuphela ezo amanani anesandi u-0. Le ndlela ilula kwaye kulula ukuba ukukhumbula. Ngenxa yoko, 500: 10 = 50.

Nantso zonke iimpawu ezisisiseko. Bakhumbule, unako ukwenza ubomi bakho lula. Kakade ke, zikho nezinye amanani apho kukho iimpawu divisibility, kodwa siza bonisa nje ezona ziphambili.

ngokucandeka Table

Kwimathematika, akukho kuphela etafileni phindo, kodwa ukwahlukana itafile. Emva kokufunda kuyo, ungenza ngokulula ukwenza lo msebenzi. Enyanisweni, le theyibhile ukwahlukana ngumbala itafile phindo. Yenza kube ngokwakho akukho nzima. Ukuze oku kufuneka kwakhona zonke umgca yezintlu phindo ngale ndlela:

1. Beka imveliso inani kwindawo yokuqala.

2. Beka uphawu lokwahlulahlula ze ubhale into yesibini ukusuka etafileni.

3. Xa kophawu olulinganayo kubhaliweyo yakha kuqala.

Umzekelo, thatha umgca olandelayo etafileni phinda 2 * 3 = 6 Ngoku ndiyibhale ngokwe algorithm, nokufumana: 6 ÷ 3 = 2.

Kaninzi, abantwana bacelwa ukuba benze itafile yabo, ngaleyo ndlela inkumbulo yabo ingqalelo.

Ukuba awunalo ixesha ubhale kuyo, ungasebenzisa i enikwe kweli nqaku.

iintlobo yokwahlukana

Masithethe kancinci malunga neentlobo sisahlula.

Okokuqala, kunokwenzeka ukuba ukwaba hlula amanani apheleleyo namaqhezu. Kwimeko yokuqala sikwazi ukuthetha malunga nokusebenza ngamanani apheleleyo kunye ngenani leshumi, kwaye eyesibini - kuphela amanani iqhezu. Kule meko kunokuba zombini kwinani iqhezu okanye, umahluli, okanye zombini ngexesha elinye. Osahluleyo kungenxa yokuba ukuba imisebenzi kumaqhezu zahluka imisebenzi apheleleyo.

Okulandelayo siza kuthetha zokwahlula amaqhekeza ngaphezulu.

Ngokusekelwe amanani, aqukiweyo lo msebenzi, iintlobo ezimbini hlula ziyakwazi ukuchongeka: on nangokungenamathandabuzo amanani multivalued. Eli candelo elula uthathwa ukuba imivo elinye. Apha, akuyi kuya kufuneka benze izibalo ezinde. Ukongeza, itafile kunokunceda kakuhle hlula. Yabelana efanayo kwelinye icala -, amanani amabini anomvo ezintathu - nzima.

Cinga imizekelo yezi ntlobo division:

14: 7 = 2 (division ngenani elinemivo enye).

240: 12 = 20 (division ngenani enamanani amabini).

45387: 123 = 369 (division ngenani elinemivo emithathu-).

Icandelo lokugqibela kuchongwa, nto leyo ibandakanya amanani akhabayo kunye navumelanayo. Xa sisebenza kunye yokugqibela kufuneka bayazi imithetho apho unika isiphumo ixabiso entle okanye embi.

Xa hlula amanani ngemiqondiso ezahlukeneyo (elingezantsi - inani liyavumelana, linokwahlulwa - negative, okanye ngenye indlela), siya ufumana inani elithabathayo. Xa hlula amanani kunye uphawu efanayo (kunye nomahlulwa, kunye, umahluli - alcohol HIV okanye vice) - ufumane okanye linani elidibanisayo.

Qwalasela le mizekelo ilandelayo ukuze ukucaciselwa:

21: (- 7) = -3

-36: 6 = (-6)

-48 (-8) = 6.

division of amaqhezu

Ngoko ke, thina bayidiliza imithetho esisiseko, wabanika umzekelo ngokwahlula inani ngenani, ngoku makhe sithethe ngendlela ukwenza ngokuchanekileyo imisebenzi efanayo ngamaqhezu.

Ngaphandle kwento yokuba ukwahlulwa amaqhekeza ekuqaleni kubonakala ngathi yinto entle kakhulu, enyanisweni, msebenzi nzima ukuze nabo. Ukwahlula amaqhekeza lwenziwa ngendlela efanayo-phinda, kodwa umahluko mnye.

Ukuze ukwahlula iqhezu, kwinani kufuneka kuqala phinda tivi yi elingezantsi, umahluli kunye ubhale isiphumo njengeendaba zangasese kwinani. Emva koko phinda phinda idinomineyitha tivi ngokuthi, umahluli kwe elingezantsi kunye nenani ukurekhoda isiphumo nje labucala.

ingenziwa lula kuyo. Phinda ubhale iqhekeza ehlukanisayo, interchanging elingezantsi ukuya nenani uze phinda amanani ngenxa.

Umzekelo, yahlula amaqhezu amabini: 4/5: 3/9. Okokuqala, vula phezu nomabi, sifumana 9/3. Ngoku phinda amaqhezu: 4/5 * 9/3 = 36/15.

Njengoko ubona, nto intle lula, yaye akukho nzima ngaphezu kwisahlulo ngenani-nenombolo eyodwa. Imizekelo amanyathelo kunye amaqhezu isonjululwe nje, ukuba anithanga ukulibala eli siko.

iziphumo

Division - enye imisebenzi zezibalo ukuba wonke umntwana afunde esikolweni aphantsi. Kukho imithetho ethile ekufuneka ukuba ukwazi ubuchule, ukuze kube lula lo msebenzi. Eli candelo ke amasalela nangaphandle, is a division of amanani akhabayo kunye iqhezu.

Khumbula iimpawu yalo msebenzi lweMathematika Kulula kakhulu. Thina lidilizwe amanqaku ezibalulekileyo ngazo akukho namnye umzekelo ngokwahlula inani ngenani noba sithetha ukuba asebenze njani na amanani iqhezu.

Ukuba ufuna ukuphucula ulwazi lwakho yemathematika, sicebisa ukuba ukukhumbula le mithetho elula. Ukongezelela, sinako icebise ukuba Ukuphuhlisa inkumbulo kunye nolwazi lokubala engqondweni, enza dictations zezibalo okanye ezama nje ukuba ukubala ngomlomo QUOTIENT amanani amabini random. Ndikholelwe, ezi zakhono soze isenokubaxeka.
