Dana spent ¹₄ of her salary on a speaker and ³₅ of the remainder on a refrigerator. If she saved the remaining $204, how much was her salary?
Fraction of the salary spent on the speaker = ¹₄

Fraction of the salary on the remainder
= 1 - ¹₄
= ³₄

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

Speaker	Remainder		Total
1x5	3x5		4x5
	Refrigerator	Savings
	3x3	2x3
5 u	9 u	6 u	20 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 3 and 5 is 15.

Total salary = 20 u

Amount spent of the speaker = 5 u
Amount spent on the refrigerator = 9 u
Amount of savings = 6 u

6 u = 204

1 u = 204 ÷ 6 = 34

Dana's salary
= 20 u
= 20 x 34
= $680

Answer(s): $680
