the ratio of the number of boys to the number of girls is 3 : 2. if each boy receives 2 pieces of paper and each girl receives 3 pieces of paper, how many children are there altogether if a total of 1992 pieces of paper are needed?

im not sure if this is right, but i got 797 children

1 answer

1992/12 = 166 groups of 5 children, or 830 in all
