The Palafoxes make $3,840 a month. They spend $1,600 for rent. What fraction of their income goes to rent?

Rent Payment Fraction = Rent Payment / Total Income
Rent Payment Fraction = 1600 / 3840

Our greatest common factor of 1600 and 3840 is 320.

So if we divide 1600 and 3840 by 320, we get:
Rent Payment Fraction = 5/12
