1.hasil dari 1 2/5 - 3/4 = 2.hasil dari 2/6 × 4/5 = 3.hasil dari 1 1/3 : 4/7 =

1. 1 2/5 - 3/4 = 7/5 - 3/4 = 28/20 - 15/20 = 8/20 = 2/5
2. 2/6 x 4/5 = 8/30 = 4/15
3. 11/3 : 4/7 = 11/3 x 7/4 = 77/12 = 6 5/12
Maaf kalo salah

1. 1 2/5 - 3/4 = 7/5 - 3/4
= 28/20 - 15/20
= 13/20
2. 2/6 x 4/5 = 8/30 = 4/15
3. 1 1/3 : 4/7 = 4/3 : 4/7
= 4/3 x 7/4
= 28/12 = 2 4/12 = 2 1/3
