Answer:

Step-by-step explanation:

ratio of 5:7 means that 5/(5 + 7) = 5/12 are boys and 7/(5 + 7) = 7/12 are girls

(5/12)(36) = 15 boys

(7/12)(36) = 21 girls

21 - 15 = 6 more girls than boys.
If you get up to 15:21 and add them together you will get 36 children so then you subtract 21-15 and will end up with 6, so the answer is 6 more girls.
