Question

1) X + 8 7/12 = 10 1/4
2) X - 9 5/9 = 10 5/6
3) 12 1/4 - X = 8 7/8
4) 4 1/4 - 3 2/3 +2 5/6 =

Answer 1

1) x+ 8 7/12= 10 3/12
x= 10 3/12 - 8 7/12
x= 9 i 15/12 - 8 7/12
x= 9  i 8/12
x= 9 i 2/3

2) x - 9 i 20/36= 10 i 30/36
x= 10 i 30/36 + 9 i 20/36
x= 19 i 50/36
x= 20 i 14/36
x= 20 i 7/18

3) 12 2/8 -x= 8 7/8
x= 12 2/8- 8 7/8
x= 11 i 10/8 - 8 i 7/8
x= 3 i 3/8

4) = 4 i 3/12- 3 i 8/12 + 2 i 5/6= 3 i 15/12- 3 i 8/12 + 2 i 10/12= 7/12 + 2 i 10/12= 2 i 17/12= 3 i 5/12
