Question

There are 18 people waiting for the train. Eight-ninths of them have an umbrella. How many people waiting for the train have an umbrella?​

Answer 1

Explanation:

Ok, so there are 18 people. If 8/9 have umbrellas, how many have umbrellas?

There is a simple solution to this.

First, lets find out how much people is 1/9

We can do this by dividing 18 by 9 to get 2

So 1/9 of the group is 2 people.

Now you can use this to find 8/9 by multiplying 2 by 8

This gives you the total of 16

Another way you could do this was take the answer from the first step and subtract that from the 18

9/9 - 1/9 = 8/9 => 18 - 2 = 16

Hope this helps! =)
