Question

1. 22/7 : 4 + 1/2 =

2. 2/7 - 1/9 : 2/9 X 1/2 -2/3 =

3. 2 4/9 X ( 6/7 - 8/1 ) =

4. 4/5 X 3/5 = 2/7 =

Answer 1

1.= 22/7 ÷ 4 + 1/2
= 22/7 ÷ 4/1 + 1/2
= 22/7 ÷ 4/1
= 22/7 × 1/4
= 22/28 + 1/2
= 22/28 + 14/28
= 36/28 = 9/7 = 1 2/9

2.= 2/7 - 1/9 ÷ 2/9 × 1/2 - 2/3
= 2/7 - 1/9
= 18/63 - 7/63
= 11/63 ÷ 2/9
= 11/63 × 9/2
= 11/14 × 1/2
= 11/28 - 2/3
= 33/84 - 28/84
= 5/84

3.= 2 4/9 × ( 6/7 - 8/1 )
= 22/9 × ( 6/7 - 8/1 )
= 8/1 - 6/7
= 56/7 - 6/7
= 50/7 × 22/9
= 1100/63 = 17 29/63
