30
30 ÷ 6 = 5
5 + 9 = 14
14 + 14 = 28
28 ÷ 7 = 4
4 x 8 = 32
32 + 32 = 64
64 + 64 = 128
128 – 100 = 28
28 ÷ 4 = 7
Answer = 7

37
37 + 29 = 66
(5/6) x 66 = 55
55 x 4 = 220
0.05 x 220 = 11
11 x 11 = 121
121 + 19 = 140
0.25 x 140 = 35
(5/7) x 35 = 25
25 x 16 = 400
Answer = 400

15
15 x 15 = 225
225 + 225 = 450
0.3 x 450 = 135
135 + 8 = 143
143 ÷ 11 = 13
13 x 13 = 169
169 – 1 = 168
168 ÷ 12 = 14
14 x 5 ½ = 77
Answer = 77
