Nicole, Risa and Victoria bought a present for their uncle. They shared the cost equally between them. Nicole used ⁴₅ of her savings, Risa used ¹₁₀ of her savings and Victoria used ³₈ of her savings. Nicole and Victoria had $253 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, 1 and 3 = 12

4x35x3 of Nicole's savings = 1x1210x12 of Risa's savings = 3x48x4 of Victoria savings
1215 of Nicole's savings = 12120 of Risa's savings = 1232 of Victoria's savings

	Nicole	Risa	Victoria
Before	15 u	120 u	32 u
Change	- 12 u	- 12 u	- 12 u
After	3 u	108 u	20 u

Savings that Nicole had left
= 15 u - 12 u
= 3 u

Savings that Victoria had left
= 32 u - 12 u
= 20 u

Total savings that Nicole and Victoria had left
= 3 u + 20 u
= 23 u

23 u = 253

1 u = 253 ÷ 23 = 11

Amount that each girl paid
= 12 u
= 12 x 11
= $132

Answer(s): $132
