Answer:

7/50

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

7/8 - 1/5 = 0.675
0.675 / 5 = 0.135
