In order to determine the percentage, let x as the percentage. Then, you can write:

[tex]\frac{x}{100}\cdot3000=2700[/tex]

factor x/100 is the percentage in decimal form. The product of this factor and 3000 equals 2700.

Solve for x and simplify:

[tex]x=\frac{2700}{3000}\cdot100=90[/tex]

Hence, teacher has used 90% of the copies.
