B. 2:3
C. 1:3
D. 1:4

Answers

Answer 1

Answer: 24 - 8 = 16
There are 16 girls in the class.
The ratio of girls to boys is therefore 16:8
16 ÷ 8 = 2
8 ÷ 8 = 1

16:8 simplified is 2:1
The answer is A.

My teacher said the answer was $44.44 but I don't understand how she got that, can someone help please?
