1.2/7 : 3/4 = 2.8/9 : 2 1/2 = 3.1 2/3 : 2 1/2 = 4.1,8 : 0,2 =

#maaf kalo salah...

1. 2/7 ÷ 3/4 = 2/7 × 4/3 = 8/21

2. 8/9 ÷ 2 1/2 = 8/9 ÷ 5/2 = 8/9 × 2/5 = 16/45

3. 1 2/3 ÷ 2 1/2 = 5/3 ÷ 5/2 = 5/3 × 2/5 = 10/15 = 10÷5/15÷5 = 2/3

4. 1,8 ÷ 0,2 = 1 8/10 ÷ 2/10 = 18/10 × 10/2 = 180/20 = 180÷10/20÷10 = 18/2 = 9
MAAF KALO SALAH
