Complete question :

Priya is stacking building blocks to make a tower. She takes a break when the tower is 2 and 1/2 feet tall, which is 5/8 of the height of the tower she wants to build. How tall is the tower when finished

4 feets

Step-by-step explanation:

Given that:

Height of building when she took a break = 2 1/2 feets

Let the entire height of the tower = x

2 1/2 feets = 5/8 of the tower height

2 1/2 feets = (5/8)x

Height of tower when finished ; fins the value of x

5/2 = 5x / 8

Cross multiply

5*8 = 2*5x

40 = 10x

Divide both sides by 10

40/10 = 10x/ 10

4 = x

Hence, height of tower when completed is 4 feets
