20
20 ÷ 2 = 10
10 + 2 = 12
12 ÷ 3 = 4
4 x 6 = 24
24 + 1 = 25
25 + 25 = 50
50 – 1 = 49
49 ÷ 7 = 7
7 x 3 = 21
Answer = 21

9
9 x 7 = 63
63 - 3 = 60
60 ÷ 4 = 15
(2/3) ÷ 15 = 10
10 x 4 = 40
40 + 2 = 42
42 ÷ 7 = 6
6 + 9 = 15
15 + 15 = 30
Answer = 30

56
56 ÷ 7 = 8
8 x 8 = 64
64 + 16 = 80
0.15 x 80 = 12
12 x 9 = 108
108 ÷ 2 = 54
54 ÷ 6 = 9
9 + 17 = 26
26 x 3 = 78
Answer = 78
