Question

Susan wants to have 30% of her gumballs be green If there are

50 gumballs in the machine, how many would have to be green?

Answer 1

15 gumballs would have to be green.

To solve this question, you would need to figure out what is 30% of 50.

First, change 30% into it's decimal form, 0.3, then multiply it with 50.

Answer 2

15 gumballs

Explanation:

There would have to be...

30%*50 green gumballs

We can start by converting 30% to a fraction. Any percentage is just that number over one hundred so...

30/100*50

We can simplify 30/100 by dividing the numerator and the denominator by 10...

3/10*50

Cancel out 10 and 50 (50/10=5)

3*5

15 gumballs would have to be green
