Eva, Gem and Elyse bought a present for their friend. They shared the cost equally between them. Eva used ⁴₉ of her savings, Gem used ³₄ of her savings and Elyse used ⁵₇ of her savings. Eva and Elyse had $1881 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 4, 3 and 5 = 60

4x159x15 of Eva's savings = 3x204x20 of Gem's savings = 5x127x12 of Elyse savings
60135 of Eva's savings = 6080 of Gem's savings = 6084 of Elyse's savings

	Eva	Gem	Elyse
Before	135 u	80 u	84 u
Change	- 60 u	- 60 u	- 60 u
After	75 u	20 u	24 u

Savings that Eva had left
= 135 u - 60 u
= 75 u

Savings that Elyse had left
= 84 u - 60 u
= 24 u

Total savings that Eva and Elyse had left
= 75 u + 24 u
= 99 u

99 u = 1881

1 u = 1881 ÷ 99 = 19

Amount that each girl paid
= 60 u
= 60 x 19
= $1140

Answer(s): $1140
