Answer 1

1) 1/4 +5/6 + 3/ 8 = 6/24 + 20/24+9/24 = 35/24 = 1 11/24
2) 31/4 + 31 /8 + 26/5 = 310/40 + 155/40 + 208/40 = 673 /40 = 16 33/40
3) 47/9 + 25/ 4 + 53 /12 = 188 + 225+159 /36 = 572 / 36 = 15 32/36 = 15 8/9
4) 1/6 - 1/9 = 6/36 - 4/36 = 2 /36 = 1 / 18
5) 23/6 - 3/8 = 92 / 24 - 9/24 = 83 /24 = 3 11 /24
6) 62/ 15 -11/18
7) 67/12 - 13/6 = 67/12- 26/12 =41/12 = 3 5/12
8) 64/9-49/12
9) 161 /16 -133/20
10) 18 /1 : 7/13 = 18/1 × 13/7 = 234/7 = 33 3/7
11) 28/3 : 17/9 = 28/3 × 9/17 = 84 /17 = 4 16 /17
12) 85/7 : 10/3 = 85/7 ×3/10 = 255/70 = 3 45/70 = 3 9/14
