Question

danielle used 8cm of tape to wrap 4 presents if danielle used 30cm of tape how many presents did she wrap

Answer 1

Answer:

15 presents

Explanation:

1. Find the amount it takes to multiply 8 by to get 30. The reason we need to find this is because we need to multiply 4 by the same number to get the amount of presents, because if you multiply one number in a relationship by some number, you have to do the same to the other number. To get from 8 to 30, you multiply by 3 3/4 (30/8).

2. Multiply 4 by that number. 4 * 30/8 (3 3/4) is equal to 30/2, which is equal to 15. This means that she wrapped 15 presents
