Question

Bella saw that 7 out of 11 people brought an umbrella to the beach. There 99 people there. How many of them did not have a beach umbrella

Answer 1

Hello!

7 out of 11 people brought an umbrella to the beach

this is a fraction of 7/11

We multiply this by 99 to get how many people brought an umbrella out of 99

7/11 * 99 = 63

You subtract this from 99 to see how many did not have an umbrella

99 - 63 = 36

The answer is 36 people

Hope this helps!
