Answer:
10%
Step-by-step explanation:
2 meters is equivalent to 200 centimeters, so just subtract the amount of wire that was used to the amount left. So it's 20/200. Simplify this fraction so the denominator is 100. Divided by 10, its 10/100.
From the fraction, we can figure out that 10% of the wire was used.
