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 [tex]=15\times\frac{1}{2}\text{inch}=7.5\text{inches}[/tex]

As she cut a 6-inch piece of string .

So the length of string she needs[tex]=7.5-6=1.5[/tex]

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

Hence, she need 3 pieces of string.
