Jaslyn spent ¹₅ of her salary on a gas stove and ²₅ of the remainder on a refrigerator. If she saved the remaining $372, how much was her salary?
Fraction of the salary spent on the gas stove = ¹₅

Fraction of the salary on the remainder
= 1 - ¹₅
= ⁴₅

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

Gas Stove	Remainder		Total
1x5	4x5		5x5
	Refrigerator	Savings
	2x4	3x4
5 u	8 u	12 u	25 u

The remainder and the total amount on the refrigerator and the savings are the same. Make the remainder and the total amount on the refrigerator and the savings the same.  LCM of 4 and 5 is 20.

Total salary = 25 u

Amount spent of the gas stove = 5 u
Amount spent on the refrigerator = 8 u
Amount of savings = 12 u

12 u = 372

1 u = 372 ÷ 12 = 31

Jaslyn's salary
= 25 u
= 25 x 31
= $775

Answer(s): $775
