There is 195 campers with the ratio of 8 to 7 how many boy campers how many girl campers

So you have 195 campers, and suppose that the ratio of 8:7 is the ratio of boys to girls. This number means that there are 8 boys for each 7 girls.

if we multiply 7 and 8 for the same number x of pairs, and think that the sum of all boys and girls must be equal to 195, we get that

x*7 + x*8 = 195

x*15 = 195

x = 195/15 = 13

so we have 13 pairs of 8 boys and 7 girls.

and the total of boys is 13*8 = 104

and the total of girls is 13*7 = 91

uhhh idk u yolo?
