Jane's and Emma's savings were in the ratio of 4 : 9. Both of them shared the cost of their younger sister's souvenir equally. Jane's remaining savings was ²₅ as much as Emma's savings. What percentage of her savings did Emma spend? Correct the answer to 1 decimal place.

	Jane	Emma	Difference
Before	4x3 = 12 u	9x3 = 27 u	5x3 = 15 u
Change	- 2 u	- 2 u
After	2x5 = 10 u	5x5 = 25 u	3x5 = 15 u

Since Jane and Emma shared the cost of their younger sister's souvenir equally, the amount each paid for the souvenir is the same. 

So, the difference in the amounts between Jane and Emma at first and in the end remains the same.  Make the difference in the amounts between Jane and Emma at first and in the end the same. LCM of 5 and 3 is 15.

Amount that Emma spent on the souvenir
= 27 u - 25 u
= 2 u

Percentage of her savings that Emma spent
= ²₂₇ x 100%
≈ 7.4%

Answer(s): 7.4%
