Question

Carl used 10 2/9 of an inch of string to tie a parcel and another 5 1/4 of an inch of string to

tie a box, how much string is left if he started with 20 inches?

Answer 1

Answer: 4 19/36 inches

Explanation:
To add the two measurements together, you need to find a common denominator. In this instance, it will be 36.

2 * 4 = 8, 9 * 4 = 36, which means our first measurement turns into 10 8/36

1 * 9 = 9, 4 * 9 = 36, which means our second measurement turns into 5 9/36

Adding these together we get 15 17/36.

Subtract this from 20.

The amount of string that is left is 4 19/36 inches.

Hope this helped!
