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.
