Risa, Kimberly and Linda bought a souvenir for their uncle. They shared the cost equally between them. Risa used ¹₄ of her savings, Kimberly used ³₅ of her savings and Linda used ⁵₆ of her savings. Risa and Linda had $384 left. How much did each girl pay for the souvenir?
The amount spent by each girl is the same.  Make the numerators the same.
LCM of 1, 3 and 5 = 15

1x154x15 of Risa's savings = 3x55x5 of Kimberly's savings = 5x36x3 of Linda savings
1560 of Risa's savings = 1525 of Kimberly's savings = 1518 of Linda's savings

	Risa	Kimberly	Linda
Before	60 u	25 u	18 u
Change	- 15 u	- 15 u	- 15 u
After	45 u	10 u	3 u

Savings that Risa had left
= 60 u - 15 u
= 45 u

Savings that Linda had left
= 18 u - 15 u
= 3 u

Total savings that Risa and Linda had left
= 45 u + 3 u
= 48 u

48 u = 384

1 u = 384 ÷ 48 = 8

Amount that each girl paid
= 15 u
= 15 x 8
= $120

Answer(s): $120
