The ratio of girls to boys at camp is 8 to 7. If there are a total of 500 kids at camp, how many of them are girls?

Answer 1

IF YOU ADD THE RATIOS 8 AND 7, YOU GET 15.

8/15 OF THE 500 SHOULD GIVE THE NUMBER OF GIRLS.

HOWEVER, WE DO NOT GET AN INTEGER. (268 2/3)

SINCE WE CAN'T DEAL WITH FRACTIONAL PEOPLE,

THE TEST WRITER CHOSE IMPOSSIBLE NUMBERS.

THEIR ERROR.

IF THE NUMBER WERE 510 INSTEAD, THEN

8/15 * 510 = 272 GIRLS.

THE TOTAL NUMBER MUST BE DIVISIBLE BY 15.
