c

Step-by-step explanation:

The answer is c

5/8 * ? = 2 1/2

Step-by-step explanation:

x is the height of tower when finished.

We know that Priya takes a break when the tower is 2 and 1/2 feet tall, which is 5/8 off the height of the tower she wants to build.

This means that 5/8 of x equals 2 and 1/2 Let us represent this information in an equation.

5/8 × x = 2 and 1/2

Convert our given mixed fraction into improper fraction.

5/8 × x = 5/2

Multiply both sides of our equation by 8/5.

(8/5 × 5/8) × x = (5/2 × 8/5)

x = 8/2

x = 4

4 feet

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
