Winnie, Dana and Pamela bought a gift for their friend. They shared the cost equally between them. Winnie used ¹₆ of her savings, Dana used ⁴₅ of her savings and Pamela used ³₄ of her savings. Winnie and Pamela had $1472 left. How much did each girl pay for the gift?
The amount spent by each girl is the same.  Make the numerators the same.
LCM of 1, 4 and 3 = 12

1x126x12 of Winnie's savings = 4x35x3 of Dana's savings = 3x44x4 of Pamela savings
1272 of Winnie's savings = 1215 of Dana's savings = 1216 of Pamela's savings

	Winnie	Dana	Pamela
Before	72 u	15 u	16 u
Change	- 12 u	- 12 u	- 12 u
After	60 u	3 u	4 u

Savings that Winnie had left
= 72 u - 12 u
= 60 u

Savings that Pamela had left
= 16 u - 12 u
= 4 u

Total savings that Winnie and Pamela had left
= 60 u + 4 u
= 64 u

64 u = 1472

1 u = 1472 ÷ 64 = 23

Amount that each girl paid
= 12 u
= 12 x 23
= $276

Answer(s): $276
