Answer: 106 boys
Step-by-step explanation: first you need to find how much 1/5 of the girls are which can be found by dividing the 160 ÷ 3 (because the girls are 3/5) which is: 160 ÷ 3 = 53.3 = 1/5 then, multiply this by 2 ( because the fraction of boys is 2/5) which is: 53.3 × 2 = 106.6 ( you don't need to round off but make it a whole number).
