    Answer: 19

    Step-by-step explanation:

    We know there are 25 boys, meaning if we divide it by 5 we can figure out that the number of girls is 15.

    25 - 16 = 9 boys went sailing

    15/3 <- - To find out how many of the girls went sailing

    dividing it by 3 would also us to have one third going climbing at the remaining 2/3 going sailing

    10 girls went sailing

    10 + 9

    =19
