1. ab^2/c : b/c = 2.x^2y^3/3z : 18xy/6 = pliss tolong jawab bsk dikumpul jika bisa tulis dikertas 1 lembar lalu di poto

1. ab²/c ÷ b/c
= ab²/c x c/b [c habis, b² ÷ b menyisakan b]
= ab

2. x²y³/3z ÷ 18xy/6
= x²y³/3z x 6/18xy [6/3z menjadi 2/z, x²y³ d bagi xy jadi xy²]
= 2xy²/18z [2/18 jdi 1/9]
= xy²/9z
