39
39 + 9 = 48
48 ÷ 4 = 12
12 x 3 = 36
36 ÷ 9 = 4
4 x 4 = 16
16 + 5 = 21
21 ÷ 7 = 3
3 x 8 = 24
24 ÷ 4 = 6
Answer = 6

79
79 + 29 = 108
(5/9) x 108 = 60
(11/12) x 60 = 55
55 x 3 = 165
165 + 3 = 168
168 ÷ 14 = 12
12 x 11 = 132
132 ÷ 4 = 33
(9/11) x 33 = 27
Answer = 27

37
37 + 19 = 56
(5/7) x 56 = 40
40 x 1.25 = 50
50 x 3 ½ = 175
175 + 175 = 350
0.04 x 350 = 14
14 x 20 = 280
0.75 x 280 = 210
0.1 x 210 = 21 + 210 = 231
Answer = 231
