Question

The ratio of boys to girls in the 9th grade is 3 to 4. There are 176 girls. Set up a proportion to model this information. A) 3/4 =b/176 B) 3/b=176 C) 3/176=4/b A) 3/4=176

Answer 1

A) 3/4 = b/176

Explanation:

Basically its saying that for every 4 girls, there are 3 boys or 3/4

How many boys would there be if there is 176 girls?

`(3)/(4) =(b)/(176)`

`b=176` ×
`3` ÷ 4 = 132

There would be 132 boys
