Question

robin needed 3 2/3 feet of thread to finish a pillow she was making. if she has 2 times as much thread as she needs, what is the length of the thread she has?

Answer 1

7 1/3

3 2/3+3 2/3=7 1/3

Answer 2

`7(1)/(3)` feet.

Explanation:

We have been given that Robin needed 3 2/3 feet of thread to finish a pillow she was making. We are asked to find the length of thread, if she has 2 times as much as thread as she needs.

First of all, we will convert
`3(2)/(3)` into improper fraction as:

`3(2)/(3)\rightarrow (3*3+2)/(3)=(9+2)/(3)=(11)/(3)`

Two times the length of thread would be:

`2*(11)/(3)`

`(2*11)/(3)`

`(22)/(3)`

`(3*7+1)/(3)`

`7(1)/(3)`

Therefore, Robin had
`7(1)/(3)` feet of thread.
