Question

Amy has 630 stickers that are organized into 42 packs. She plans to give 3 packs to her friends. How many stickers is she giving away?

Answer 1

It's a probability

1 pack = x stickers

42 pack = 630 stickers

Cross Multiply

42 pack x stickers = 630 ×1 pack

= 630

Divide ( ➗) both sides by 42

x stickers = 630/ 42

x= 15

Answer 2

45 stickers

Explanation:

630/42 = 15 (represents the number of stickers in each pack)

Since there ar 3 packs, we multiply 15 by 3.

3 x 15 = 45

45 stickers.

tadah!
