Joelle spent ²₅ of her salary on a refrigerator and ³₅ of the remainder on a washing machine. If she saved the remaining $222, how much was her salary?
Fraction of the salary spent on the refrigerator = ²₅

Fraction of the salary on the remainder
= 1 - ²₅
= ³₅

Fraction of the remainder on savings
= 1 - ³₅
= ²₅

Refrigerator	Remainder		Total
2x5	3x5		5x5
	Washing Machine	Savings
	3x3	2x3
10 u	9 u	6 u	25 u

The remainder and the total amount on the washing machine and the savings are the same. Make the remainder and the total amount on the washing machine and the savings the same.  LCM of 3 and 5 is 15.

Total salary = 25 u

Amount spent of the refrigerator = 10 u
Amount spent on the washing machine = 9 u
Amount of savings = 6 u

6 u = 222

1 u = 222 ÷ 6 = 37

Joelle's salary
= 25 u
= 25 x 37
= $925

Answer(s): $925
