Answer:
the number of Boys = 104
and the number of Girls = 91
Explanation:
given;
ratio of boys to girls is 8:7
if there are a total of 195 campers
find:
how many boys are there and how many girls
B + G = 195 -----equation 1
use the ratio and proportion
8 = 7
B G
7B = 8G
B = 8G / 7 ---substitute into the equation 1
B + G = 195
8G + G = 195
7
15 G = 195
7
15 G = 195(7)
15 G = 1365
G = 1365 / 15
G = 91
solve for the number of Boys
B = 8G / 7
B = 8(91) / 7
B = 104
therefore,
the number of Boys = 104
and the number of Girls = 91
