Answer 1

1) 4 1/12 - 1/6 = 4 1-2/12 = 3 13-2/12 = 3 11/12
2) 9 11/24 - 7 19/36 = 2 33-38/72 = 1 105-38/72 = 1 67/72
3) 5 5/9 - 2 4/7 = 3 35 - 36/ 63 = 2 98-36 = 2 62/63
4) 9 8/35 - 2 52/105= 7 24 -52/ 105= 6 129 - 52/105 = 6 77/105

x - 7 1/3 = 12 5/12
x=12 5/12 + 7 1/3= 19 5+4/12 = 19 9/12
x= 19 9/12



11 7/9 - x = 8 5/7
x= 11 7/9 - 8 5/7 = 3 49-45/63 = 3 4/63
