A) what is the ratio girls to boys in the class?
B) what is the ratio boys to girls in the class

Answer 1

Answers:

Ratio of girls to boys is 2:1

Ratio of boys to girls is 1:2

==========================================================

Step-by-step explanation:

2/3 of the class are girls. If the class had 3 people, then 2 of them are girls. The remaining 3-2 = 1 person is a boy.

The ratio of girls to boys has us list the number of girls (2) followed by the number of boys (1). Separate the values with a colon. That's how we end up with 2:1

The ratio of boys to girls will have us flip that previous ratio to get 1:2

The order is important when it comes to forming ratios.

Answer 2

a) 2:1
