Jul 9, 2016

#x = $300#

Explanation:

Write the question in English first and then in maths:

6% of what amount will be equal to $18?

#6/100 xx x = 18#

#x = 18 xx 100/6#

#x = $300#

Or use a comparison method with direct proportion.

"If 6% is $18, 100% will be how many $?"

#6/18 = 100/x " "%/$#

Or# x/100 = 18/6#
