Izingxenyana ezifanele yilezo kusuka ekuhlukanisweni phakathi kwezinombolo ezimbili, lapho inombolo noma isabelo (leyo etholakala engxenyeni engenhla yengxenyenamba) incane kune-denominator noma isihlukanisi (leyo etholakala ezansi kwengxenyenamba ephansi).
Bhekafuthi: Izibonelo Zezingxenyana
Zivezwa kanjani?
Ngale ndlela, izingxenyana ezifanele zingabonakaliswa kusetshenziswa inombolo engaphansi kuka-1, okungukuthi, inombolo eyi-fractional esebenzayo.
Umqondo wengxenyenamba efanele ulula: udinga nje igrafu noma yisiphi isibalo sejiyometri esihlukaniswa kalula sibe izingxenye ezilinganayo (isibonelo, indingilizi, lapho izingxenye zingamakwa njengezipikha zebhayisikili) bese ulihlukanisa libe yizingxenye eziningi ezilinganayo nenombolo evela kwinani elingaphezulu.
Ngemuva kwalokho, izingxenye eziningi njengoba kukhonjisiwe kwinombolo zingaklwebheka noma zifakwe umbala, ingxenyenamba efanele izomelwa ngale ndlela.
Abantu bavame ukuhlobanisa umqondo wengxenyenamba nezingxenyana zabo, ngoba empilweni yansuku zonke kuvame kakhulu ukuthengiswa isisindo kwemikhiqizo yokudla ehlukile ngale ndlela, enikela ‘ngekota eyodwa’, ‘uhhafu’ noma ‘amakota amathathu’ ikhilogremu yento, zonke lezi zingxenyana kungokwazo, zingaphansi kweyodwa.
Izici
Isici se- izingxenyana ezifanele lokho ngezinhloso eziningi imelwe kakhulu ngamaphesentiKuluhlobo "lomhlangano" ukuveza ubukhulu ngokuya ngenombolo eyikhulu.
Indlela yokwenza ukuhunyushwa kwengxenyenamba efanele (nayo engafanelekile, ngendlela) kufomu lephesenti ngifuna inamba eguqula ingxenyenamba ibe okulingana ne-denominator 100, kusetshenziswa 'umthetho wabathathu' wohlobo A (isibalo senombolo) kuye ku-B (i-denominator) njengoba u-X emele u-100, emele ku-X iphesenti elifunwayo.
Ngokungafani ne- Izingxenyana ezingafanele (izingxenyana ezingaphezulu kobunye), izingxenyana ezifanelekile azikwazi ukuphinda zivezwe njengenhlanganisela phakathi kwenombolo ephelele nenye ingxenyenamba, ngoba lokhu kungadinga ukuthi yonke inombolo ibe ngu-0.
Izingxenyana ezifanele ezibalweni
Emkhakheni wezibalo, ukusebenza phakathi kwezingxenyana ezifanele kulandela imithetho ejwayelekile yokusebenza phakathi kwamaqhezu: ukwengeza nokususa kuyadingeka ukuthola okujwayelekile kusetshenziswa izingxenyana ezilinganayo.Ngenkathi imikhiqizo nama-quotients kungadingeki ukuphinda le nqubo.
Futhi kungaqinisekiswa ukuthi umkhiqizo phakathi kwezingxenyana ezimbili ezifanele uyohlala uyingxenyana yohlobo olufanayo, kuyilapho i-quotient phakathi kwezingxenyana ezimbili ezifanele izodinga ukuthi enkulu ikwazi ukusebenza njenge-denominator futhi ibe yingxenyana efanele.
