Imizekelo yamaqhezu

Inkqubo ye- amaqhezu are Iimpawu zemathematika ezimele umda phakathi kwamanani amabini. Kungenxa yesi sizathu le nto iqhekeza linxulunyaniswa ngokupheleleyo nokusebenza kwesahlulo, enyanisweni kunokuthiwa iqhekeza lisahlulo okanye i-quotient phakathi kwamanani amabini.

Ukuba yi-quotient, amaqhezu inokuchazwa njengesiphumo sayo, oko kukuthi, inani elikhethekileyo (Inani elipheleleyo okanye idesimali), ukuze zonke zichazwe njengamanani. Kananjalo ngengqondo echaseneyo: onke amanani anokuphinda abonakaliswe njengamaqhezu (Amanani apheleleyo akhawulwe njengamaqhezu kunye nedinomineyitha 1).

Ukubhalwa kwamaqhezu kulandela le patheni ilandelayo: mabini amanani abhaliweyo, enye ingentla kwenye kwaye yahlulwe liphakathi, okanye yahlulwe ngomgca oxwesileyo, ngokufanayo naleyo ibhaliweyo xa ipesenti (%) imelwe. Inombolo engentla yaziwa njenge inani, kule ingezantsi njenge idinomineyitha; le yokugqibela yenye isebenza ngokwahlulahlula.

Umzekelo, iqhezu elingu-5/8 limele isi-5 esahlulwe ngo-8, ngoko ke silingana no-0.625. Ukuba inani elingezantsi likhulu kunedinomineyitha oko kuthetha ukuba iqhezu likhulu kunecandelo, inokuphinda ibonakaliswe njengexabiso elipheleleyo kunye neqhezu elincinci kune-1 (umzekelo, 50/12 ilingana no-48/12 kunye no-2/12, oko kukuthi, 4 + 2/12).

Ngale ndlela kulula ukuyibona loo nto inani elifanayo linokuphinda libonakaliswe ngenani elingenasiphelo lamaqhezu; ngendlela efanayo apho u-5/8 azakulingana no-10/16, 15/24 kunye no-5000/8000, ahlala elingana no-0.625. La maqhezu abiziwe ezifanayo kwaye gcina i ulwalamano ngokuthe ngqo.

Kwimihla ngemihla, amaqhezu abonakaliswa ngokubanzi ngamanani amancinci anokubakho, kuba elona nani lincinci lincinci lifunwa elenza inani elingezantsi liphelele. Kumzekelo wamaqhezu angaphambili, akukho ndlela yokunciphisa nangakumbi, kuba akukho linani lingaphantsi kwe-8 ekwahlulahlulayo isi-5.

Amaqhezu kunye nokusebenza kwezibalo

Ngokubhekisele kwimisebenzi esisiseko yezibalo phakathi kwamaqhezu, kufanele kuqatshelwe ukuba i isixa kwaye i ukuthabatha Kuyimfuneko ukuba iidinomineyitha zingqinelane kwaye, ke ngoko, ubuncinci obuninzi obuqhelekileyo kufuneka bufunyanwe ngokulingana (umzekelo, 4/9 + 11/6 ngu-123/54, kuba 4/9 ingama-24/54 kunye no-11/6 Ngama-99/54).

Ukwenzela i Ukuphindaphindwa kwaye i izahlulo, Inkqubo ilula noko: kwimeko yokuqala, ukuphinda-phinda phakathi kwamanani kusetyenziswa ngaphezulu kokuphindaphinda phakathi kweedinomineyitha; kweyesibini, ukuphinda-phinda kuyenziwa 'umlo'.

Amaqhezu kubomi bemihla ngemihla

Kufuneka kuthiwe amaqhezu yenye yezinto zezibalo ezibonakala rhoqo kubomi bemihla ngemihla. Isixa esikhulu se iimveliso zithengiswa zichazwe njengamaqhezuNokuba ziikhilogremu, ilitha, okanye nokuba yeyiphi na into engacacanga neyasekwa ngokwembali yezinto ezithile, ezinje ngamaqanda okanye ii-invoyisi, ezihamba ishumi elinambini.

Ke 'sinesiqingatha seshumi', 'ikota yekilo', 'isaphulelo seepesenti ezintlanu', 'inzala yeepesenti ezintathu, njl., Kodwa zonke zibandakanya ukuqonda umbono weqhezu.
