Question

Ana made 12 rainbow loom bracelets in 3 hours. how many can she make in 15 hours

Answer 1

12 bracelets in 3 hrs.....12/3 = 4 bracelets per hr

in 15 hrs...
15 * 4 = 60 <=== she can make 60 bracelets

Answer 2

To solve this, we must see a ratio between 3 hours and 15 hours.

12/3=x/15
15 is 5 times larger than 3. Therefore, if we multiply 12 by 5, we will know how many bracelets Ana can make.

12×5= 60

Therefore, 60 bracelets can be made in 15 hours
