Nicole spent ¹₈ of her salary on a gas stove and ²₃ of the remainder on a microwave oven. If she saved the remaining $238, how much was her salary?
Fraction of the salary spent on the gas stove = ¹₈

Fraction of the salary on the remainder
= 1 - ¹₈
= ⁷₈

Fraction of the remainder on savings
= 1 - ²₃
= ¹₃

Gas Stove	Remainder		Total
1x3	7x3		8x3
	Microwave Oven	Savings
	2x7	1x7
3 u	14 u	7 u	24 u

The remainder and the total amount on the microwave oven and the savings are the same. Make the remainder and the total amount on the microwave oven and the savings the same.  LCM of 7 and 3 is 21.

Total salary = 24 u

Amount spent of the gas stove = 3 u
Amount spent on the microwave oven = 14 u
Amount of savings = 7 u

7 u = 238

1 u = 238 ÷ 7 = 34

Nicole's salary
= 24 u
= 24 x 34
= $816

Answer(s): $816
