15 pieces times 0.5 equals 7.5 inches. 7.5 in-6in= 1.5 inches. 1.5 inches/0.5 inches= 3 pieces. She would need 3 more pieces.

Answer: 3 pieces of string.


Step-by-step explanation:

Given: Li needs 15 pieces of string each 1/2 inch long.

Thus, total string required by Li =15\times\frac{1}{2}\text{inch}=7.5\text{inches}

As she cut a 6-inch piece of string .

So the length of string she needs=7.5-6=1.5

Since, each piece of string has length 1/2 inch or 0.5 inch, then the number of pieces she need =\frac{1.5}{0.5}=3

Hence, she need 3 pieces of string.
