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

	Jade	Nora	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 Jade and Nora shared the cost of their older sister's present equally, the amount each paid for the present is the same. 

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

Amount that Nora spent on the present
= 27 u - 25 u
= 2 u

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

Answer(s): 7.4%
