Answer:
Step-by-step 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! =)
