Kasrlarning boʻlinishi

Kasrlarni boʻlish – oʻzaro (teskari) koʻpaytirish bilan bir xil.

Misol uchun:

start fraction, 3, divided by, 4, end fraction, start color #e07d10, divided by, end color #e07d10, start fraction, start color #11accd, 2, end color #11accd, divided by, start color #1fab54, 3, end color #1fab54, end fractionequals, start fraction, 3, divided by, 4, end fraction, start color #e07d10, times, end color #e07d10, start fraction, start color #1fab54, 3, end color #1fab54, divided by, start color #11accd, 2, end color #11accd, end fraction

Agar masalamiz koʻpaytirishga oid boʻlsa, oldin suratlarni, keyin maxrajlarni koʻpaytiramiz.
