Indlela ukuguqulela kwimizuzu ukuya kwiiyure, and vice versa: imizekelo, iindlela, amathuba umdla

Makhe sijonge ngokucacileyo indlela yokuguqulela imizuzu ibe ziiyure, kwaye vice versa. Okokuqala, siyavuma ukuba kufuneka ulwazi arithmetic kuyimfuneko. Ngapha koko, akukho ubalo akonelanga. Ukuba uzenze engqondweni yakho okanye kwi kwiphetshana ayikasebenzi, ngoko ukusebenzisa isixhobo sokubala. Ezi zinto zilandelayo ziya kuqhutywa kuzo zonke iinketho yendlela ukuguqulela imizuzu ibe ziiyure.

Ukususela kumaxesha amandulo le langoku

Jonga dial. kumacandelo 60, ngamanye imizuzwana 60 (imizuzu). Ngubani na abahlobo kunye izibalo, wabona ukuba le inzululwazi ifana iqhinga, ngokukaTau, ngaloo babedla. abantu bamandulo ngaminye bit njengoko smart bexesha zethu, phezu koko, nditsho into aphumelele.

Into esinayo namhlanje:

• 1 iyure - nto Imiz 60;.
• It ilingana umzuzu 1 imizuzwana 60;
• iyure-1 iqulethe imizuzwana 3600.

Kakade ke, 3600 efunyanwa phinda seconds imizuzu engama-60 imizuzwana 60 *. Makhe siphinde sijonge kwi clock, umzekelo, ngeyure (Utolo ezimfutshane) kwi-12, kwaye ngomzuzu (elide) - ibonisa ukuba ngoku imizuzu engama-20. Oko kukuthi, imizuzu yokuqala engamashumi amabini. Ngoku khawucinge indlela yokuguqulela kolunye ulwimi imizuzu ibe ziiyure nalo umzekelo.

izibalo ezilula kunye nezintsonkothileyo 1 chasa

Cinga arithmetic esikolweni cebetshu grade 5: kwakukho shot. Yintoni sivame? 1 iyure = 60 imiz nganye. Kwaye ukuba imizuzu engama-20 kuphela. Kunokuba ngokuchanekileyo yaphawula ukuba kwathabatha iiyure 20/60 kuphela. Kodwa siyazi ukuba iqhezu nga lincitshiswe. Masiyenze:

20/60 = 1/3.

Total Kwadlula iiyure 1/3, okanye ukuba isabelo yi 0,33.

Makhe siqwalasele omnye ukhetho: oko kukuthi ikota yeyure? Indlela ukuguqulela imizuzu ibe ziiyure phezu koko?

iiyure 1/4 = imizuzu eli-15. Njani ukuba yenzeke?

15 imiz. / Min 60. = 1/4.

Indlela ukuba abhale imizuzu eli-10 kule wotshi? izisombululo Technology indentichna:

10 imiz. / Min 60. = Iiyure 1/6 = iiyure 0.167. Kucacile ukuba irekhodi enjalo ayilunganga, ngoko imizuzu eli-10 kucetyiswa ukuba aguqulele.

Ngaphezu kweyure

Abaninzi kuthi baye babona indlela, umzekelo, nâzo namazwana nelo lokuqhubeka umboniso: 150 imiz. Indlela ukuguqulela imizuzu ibe iiyure kule meko? Kucelwa niqaphele ukuba kuya kubakho amaqhezu. Kutheni? Ngenxa kwicandelo yangaphambili, yayilixesha eyathatha iyure ngaphantsi kwe-1. Kwaye ngoku ke enye indlela ngeenxa zonke. Khangela esandleni lowo yonke into aya kuba lula, kodwa kucacile nzima ngakumbi.

Ngoko ke, emva kwemizuzu 150. Ngoko elide akazange acinge, makhe ashwankathele iingcinga imizuzu engama-60 ukuya logama nje zifike Kwinkokheli ZakwaLizwi 150: 60 imiz. + 60 imiz. = 120. Kuyimfuneko ukuba sime, kuba ukuba omnye imizuzu engama-60 wongezelela, apho kuya kubakho 180, kwaye kufuneka enyanisweni movie yimizuzu 150 kuphela. Ukubuyela imizuzu zethu 120. Kakade ke, ukuba 2:00. Ngoku imizuzu 150 thabatha 120. ukunika 30.

Ungakwenza oko ngendlela eyahlukileyo. Yeka umzuzu kunye 120 ngengqondo ukubamba kulahleke isiqingatha seyure. Apha unayo iziphumo: imizuzu 150. = Iiyure ezi-2 nemizuzu engama-30. = Iiyure 2.5.

Nendlela ukufumana iiyure 1.5 imizuzu? Kwangoko lengqondo iyure-1 30 imiz:. + 30 = imizuzu engama-60 90.

Kungenjalo, omnye iqhekeza izibalo yonke kunye nezahlulo ezintlanu-, emva yokuguqula: 15/10 = 3/2. Enyanisweni iiyure 1.5 - seyure 3/2.

Khawube nomfanekiso isifundo eklasini-3, nto leyo ehambisana ngamaqhezu. kusekho Bekukho imifanekiso umbala ezibonisa oko kuthethwa 5/6 okanye 1/2.

Kutheni iyafuneka yokuntsonkotha?

Cinga nje ukuba ishedyuli ukufunda koololiwe. Ngokuqhelekileyo, bhala, umzekelo, ukuhamba ixesha: iyure e-1 nemizuzu engama-5. Kubonakala ukuba kucace gca. Kodwa ke cinga indlela kakhulu imizuzu? imizuzu 65. Okunye: Iiyure ezi-2 nemizuzu engama-35? Makhe ukubala:

iiyure 2 = imizuzu 120, yongeza elinye imizuzu 35. Ngamafutshane: 120 + 35 = 155 imiz.

Ngoko ke sijonge indlela ukuguqulela kwimizuzu zibe iiyure, kwaye vice versa. Ukuze bakwazi ukubala ngokukhawuleza, kungakuhle ukuba bazazi iziseko lwemathematika. Ukuba awukwazi ngokwasengqondweni ukubala olungele ukusombulula ingxaki kuxwebhu.
