Question

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

Answer 1

36

Explanation:

`99/11=9`

multiply 9 by 7 (out of the 11).
`9*7=63`

63 HAVE an Umbrella, so subtract 63 from 99:

`63-99=36` people don't have an umbrella.
