Reasons:

1 0.169 ÷ 0.013 + 4 = 0.013 + 4 = 4.013
3 40 + 20 + 32 = 92
4 35/0.07 = (35 × 100) /7 = 500
5 25 + 5 × 0.2 = 13x = 25 + 1 = 13x
26 = 13x, x =2
6 81 ÷ 9 + 8 × 3 = x
9 + 8 × 3 = x
31 = x
8 12x = 144
x = 12
10 14/5 × 15/7 × 7/6 = x/21
21/3 = x/21
441/3 = x, x = 147
11 50% of 100 = 4x/8
50/100 × (100) = 4x/8
400 = 4x, x = 100
14 x+ y = 125 ---(1)
x – y = 101 ---(2)
Add
2x = 226, x = 113
Put in (1)
113 + y = 125
y = 12
16 Because 1 +1 + 4 = 6
Which is divisible by 3
