I've missed a lot of math in the past few years so I'm a bit behind. I need to solve this question using reciprocals.

15.6 + 5.5
-------------
18.1(11.1-9.2)

solve the top...then the bottom

then divide
for example: 15.6 +5.5=21.1

then do what's in the parenthesis on the bottom and multiply it with 18.1

then you can divide
:)
