Question

Darion needs 20 pieces of string. 3/8 inch in length. He cut a 4 7/8 inch piece of string into pieces that are 3/8 of an inch long each. How many more pieces of string does he need?

Answer 1

He needs 5 more pieces of string , each of 3/8 inch in length.

Explanation:

Darion needs 20 pieces of string , 3/8 inch in length.

If he cuts a 47.8 inch piece of string into pieces that are 3/8 of an inch long each, then he will get,

`[ \frac {(47)/(8)}{(3)/(8)} ]`

=
`[(47)/(8)]`

= 15 number of strings.

So he does need, (20 - 5) = 5 strings more each of 3/8 inch of length.
