Okwezinombolo
Izinkinga zomsebenzi zimayelana namazinga: ingxenye engakanani yomsebenzi eyenziwa ngehora. Amazinga ayahlanganiswa; izikhathi azihlanganiswa.
Abasebenzi abangu-19 bakha udonga ezinsukwini ezingu-18. Abasebenzi abangu-18 bangathatha izinsuku ezingaki, uma besebenza ngesivinini esifanayo?
Khetha impendulo
Imibuzo yokuqala engu-10 yesigaba ngasinye mahhala.
Imibuzo emithathu exazululiwe yalolu hlobo. Zama ngamunye kuqala, bese ufunda impendulo nendlela yokuyithola.
Isibonelo 1
Abasebenzi abangu-19 bakha udonga ezinsukwini ezingu-15. Abasebenzi abangu-5 bangathatha izinsuku ezingaki, uma besebenza ngesivinini esifanayo?
Impendulo elungile: C
Indlela yokuxazulula
Abasebenzi nezinsuku kuhambisana ngokuphambene: uma abasebenzi beba baningi, izinsuku ziba zimbalwa. Umsebenzi wonke = 19 × 15 = 285 (abasebenzi × izinsuku). Ngabasebenzi abangu-5: 285 ÷ 5 = izinsuku ezingu-57.
Isibonelo 2
Abasebenzi abangu-24 bakha udonga ezinsukwini ezingu-40. Abasebenzi abangu-2 bangathatha izinsuku ezingaki, uma besebenza ngesivinini esifanayo?
Impendulo elungile: C
Indlela yokuxazulula
Abasebenzi nezinsuku kuhambisana ngokuphambene: uma abasebenzi beba baningi, izinsuku ziba zimbalwa. Umsebenzi wonke = 24 × 40 = 960 (abasebenzi × izinsuku). Ngabasebenzi abangu-2: 960 ÷ 2 = izinsuku ezingu-480.
Isibonelo 3
Abasebenzi abangu-9 bakha udonga ezinsukwini ezingu-14. Abasebenzi abangu-21 bangathatha izinsuku ezingaki, uma besebenza ngesivinini esifanayo?
Impendulo elungile: C
Indlela yokuxazulula
Abasebenzi nezinsuku kuhambisana ngokuphambene: uma abasebenzi beba baningi, izinsuku ziba zimbalwa. Umsebenzi wonke = 9 × 14 = 126 (abasebenzi × izinsuku). Ngabasebenzi abangu-21: 126 ÷ 21 = izinsuku ezingu-6.
