Gwen, Nicole and Pamela bought a present for their neighbour. They shared the cost equally between them. Gwen used ⁵₉ of her savings, Nicole used ¹₄ of her savings and Pamela used ³₄ of her savings. Gwen and Pamela had $187 left. How much did each girl pay for the present?
The amount spent by each girl is the same.  Make the numerators the same.
LCM of 5, 1 and 3 = 15

5x39x3 of Gwen's savings = 1x154x15 of Nicole's savings = 3x54x5 of Pamela savings
1527 of Gwen's savings = 1560 of Nicole's savings = 1520 of Pamela's savings

	Gwen	Nicole	Pamela
Before	27 u	60 u	20 u
Change	- 15 u	- 15 u	- 15 u
After	12 u	45 u	5 u

Savings that Gwen had left
= 27 u - 15 u
= 12 u

Savings that Pamela had left
= 20 u - 15 u
= 5 u

Total savings that Gwen and Pamela had left
= 12 u + 5 u
= 17 u

17 u = 187

1 u = 187 ÷ 17 = 11

Amount that each girl paid
= 15 u
= 15 x 11
= $165

Answer(s): $165
