Question

Bart needs 18 pieces of string 35 inch in length. He cut a 825inch piece of string into pieces that are 35 of an inch long. How many more pieces of string does he need? Show your work.

Answer 1

He needs 4 more pieces

Explanation:

Here, we want to know the number of more string pieces that are needed

Firstly, we need to the number of string pieces obtained from the 8 2/5 inch piece

we divide 8 2/5 by 3/5

That will be;

42/5 * 5/3 = 14

So what he will get is 14 pieces from the 8 2/5 inch

The number of pieces needed is thus;

18-14 = 4
