Make a proportion and solve!

Explanation:

15/100 = x/60

we can cross multiply because they are 'equal' proportions now.

60*15 = 900

100*x = 100x

100x = 900

divide by a form of one to isolate variable further in this case 100/100

(100x)/100= 900/100

x = 9 is your number

9 is 15% of 60.

Explanation:

You can set up a proportion to solve this problem. If 15% is technically 15/100, and you want to find what number will make the same fraction with x/60, you can cross-multiply them and find x.

x/60 * 15/100 Cross multiply. darr
100x=900 Divide both sides by 100 to isolate x. darr
x=9

Thus, 9/60 = 15/100. 9 is 15% of 60.
