Question

The ratio in size of Gabriel's room to her brother Giorgio's room was 5:3.The area of Gabrielle's room was 240 square feet.If Giorgio's room was square-shaped, what was the length of his room?​

Answer 1

240:144

Explanation:

5:3

240 ÷ 5 = 48

48 * 3 = 144

In other words...

240 (Gabriel's room size) ÷ 5 (Gabriel's original room size) = 48

so if 5 times 48 = new number

then... 3 times 48 = answer!!
