20
20 ÷ 4 = 5
5 x 8 = 40
40 + 2 = 42
42 ÷ 2 = 21
21 ÷ 3 = 7
7 x 7 = 49
49 + 9 = 58
58 – 30 = 28
28 ÷ 4 = 7
Answer = 7

171
171 ÷ 9 = 19
19 x 2 = 38
38 x 2 = 76
76 x 2 = 152
152 – 8 = 144
(5/12) x 144 = 60
0.75 x 60 = 45
(2/9) x 45 = 10
10 x 10 = 100
Answer = 100

400
0.08 x 400 = 32
5 x 32 = 160
(7/8) x 160 = 140
0.175 x 140 = 24 ½
24 ½ + 24 ½ = 49
(4/7) x 49 = 28
2 ¼ x 28 = 63
63 ÷ 3 = 21
21 x 2 1/3 = 49
Answer = 49
