Question

Jasjeet and her brother collect stamps.

When Jasjeet gives her brother 1% of her stamps, she has 2475 stamps left.
Calculate how many stamps Jasjeet had originally.

Answer 1

She had 2,500 stamps before she gave 1% to her brother, since 2,475 is 99%, i just calculated this equation: p/w = a/100

Answer 2

2500

Explanation:

If Jasjeet gave away 1%, that means she has 99% left.

Put the 99% over 100, so you can drop the % sign.

Then you're going to cross multiply that with 2475/ ?. The ? is the unknown aka original ammount of stamps. The 2475 is the 99% of stamps she still has.
