Increase by 100%

Step-by-step explanation:

To find the percent increase/decrease:

Subtract the original value from the new value. Divide by the original value. Multiply the decimal by 100 to convert to a percent.

Follow these steps below. Notice the fractions 1/2 and 1/4 have been converted to decimals to more easily work with them. Remember 1/2 = 0.5 and 1/4 = 0.25.

1/2 - 1/4 = 0.5 - 0.25 = 0.25

0.25/0.25 = 1

1*100 = 100%
