Victoria, Pamela and Opal bought a gift for their mother. They shared the cost equally between them. Victoria used ⁵₉ of her savings, Pamela used ¹₈ of her savings and Opal used ³₅ of her savings. Victoria and Opal had $528 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 5, 1 and 3 = 15

5x39x3 of Victoria's savings = 1x158x15 of Pamela's savings = 3x55x5 of Opal savings
1527 of Victoria's savings = 15120 of Pamela's savings = 1525 of Opal's savings

	Victoria	Pamela	Opal
Before	27 u	120 u	25 u
Change	- 15 u	- 15 u	- 15 u
After	12 u	105 u	10 u

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

Savings that Opal had left
= 25 u - 15 u
= 10 u

Total savings that Victoria and Opal had left
= 12 u + 10 u
= 22 u

22 u = 528

1 u = 528 ÷ 22 = 24

Amount that each girl paid
= 15 u
= 15 x 24
= $360

Answer(s): $360
