Hello! I need help. Please explain how you got the answer.​

4/15

Step-by-step explanation:

Since Hannah spent 1/3 of the money on books and 2/5 of the money on presents, she currently has 1/3 * 900 = 300 dollars gone on books and 2/5 * 900 = 360 dollars gone on presents. Adding them, she has a total of 660 dollars gone on both books and presents. Now, we need to find the fraction of the 900 dollars that she has left. We need to divide the remaining money (900 - 660 = 240) by the total money she had to figure that out.

240 / 900 = 4/15

Step-by-step explanation:

do 900, split into thirds which is 300 then its 1/3 so you only have 600 left then 600 split into 5ths is 120 and  there is 2/5, which means she will have

360 left i am pretty sure, if this helps plz mark me brainliest
