Question

6/7 : 3/5 *1 2/5=
11/23*3 2/7 :5 1/2=
1 1/8 *(9 1/3 :1 3/4)=

Answer 1

6/7 : 3/5 · 1 2/5 = 2

1) 6/7 : 3/5 = 6/7 · 5/3 = (2·5)/(7·1) = 10/7

2) 10/7 · 1 2/5 = 10/7 · 7/5 = 10/5 = 2

11/23 · 3 2/7 : 5 1/2 = 2/7

1) 11/23 · 3 2/7 = 11/23 · 23/7 = 11/7

2) 11/7 : 5 1/2 = 11/7 : 11/2 = 11/7 · 2/11 = 2/7

1 1/8 · (9 1/3 : 1 3/4) = 6

1) 9 1/3 : 1 3/4 = 28/3 : 7/4 = 28/3 · 4/7 = (4·4)/(3·1) = 16/3

2) 1 1/8 · 16/3 = 9/8 · 16/3 = (3·2)/(1·1) = 6
