Li needs 15 pieces of string each 1/2 of a inch long. she cut a 6-inch piece of string into pieces that are each 1/2 of an inch long. how many more pieces of string does she need

Li need 3 more pieces of string

Solution:

Given, Li needs 15 pieces of string each of a inch long.

She cut a 6-inch piece of string into pieces that are each of an inch long.  

Now, let us find how many pieces she got from 6 inch string.

Then, she will get 12 pieces from 6 inch string.

Number of pieces she need more = total number of pieces she need – available pieces  

= 15 – 12 = 3

Hence, she need 3 more pieces.
