Question

5/9 + 1 5/7 * ( 4 2/3 -2 5/8) /1 3/4 = 2 - 3 1/7* ( 2 - 1 9/11) / 8/21 =

Answer 1

1) 5/9+1 5/7*(4 2/3-2 5/8):1 3/4= 2 5/9
1. 4 2/3-2 5/8= 2 1/24
2. 1 5/7*2 1/24= 3 1/2
3. 3 1/2:1 3/4= 2
4. 5/9+2= 2 5/9

2) 2-3 1/7*(2-1 9/11):8/21= 1/2
1. 2-1 9/11= 2/11
2. 3 1/7*2/11= 4/7
3. 4/7:8/21= 1 1/2
4. 2-1 1/2= 1/2
