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
Answer:
4 feets
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
