Sean has a piece of string 7/8 meter long. He uses 1/5 of the piece of string to tie a package and cuts the rest into 5 equal pieces. What is the length of each piece

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
