Explanation:

This is asking "7% of what number is equal to 117?"

Let the unknown number be #x#

Write an equation to reflect what is written above in English ...

#7/100 xx x = 117#

#x = 117 xx100/7#

#x = 1671 3/7#

If we write this as a decimal it will be #1671.429# to 3 decimal places. However, it is a recurring decimal and will need to be rounded at some stage. Therefore it is more accurate to give the answer as a fraction.
