Answer 2

B) 2 2/3 + 3 1/2 = 2 4/6 + 3 3/6 = 5 7/6 = 6 1/6
6 1/6 * 6 = 37/6 * 1/6 = 37/36 = 1 1/36
c) 3 * 1/4 = 3/4
2/9 * 3 = 6/9 = 2/3
3/4 - 2/3 = 9/12 - 8/12 = 1/12
d) 2 * 1 2/3 = 2 4/3 = 3 1/3
3/4 * 8 = 24/8 = 3
5 1/2 - 3 1/3 = 5 3/6 - 3 2/6 = 2 1/6
2 1/6 * 3 = 6 3/6 = 6 1/2
e) 4/5 - 3/4 = 16/20 - 15/20 = 1/20
1 2/3 + 5/6 = 1 4/6 + 5/6 = 1 9/6 = 2 3/6 = 2 1/2
1/20 * 2 1/2 = 1/20 * 5/2 = 5/40 = 1/8
