Shawn had a piece of string 1/2 m long. He used 1/3 of it to tie a box. Find the length of the string which was used to tie the box.

7/50

Step-by-step explanation:

First we have to find how much string we are going to cut into 5 pieces. We do this by taking 1/5 of 7/8 meter.

1/5 × 7/8 = 7/40

Now we have to subtract this from the original amount...

7/8 - 7/40 =

35/40 - 7/40 =

28/40 = 14/20 = 7/10

Now we divide this remaining string by 5 to find the length of the individual pieces...

7/10 ÷ 5 =

7/10 × 1/5 =

7/50 meter
