Convert Fraction into a Percent So, to find what is as a percentage, multiply the fraction by 100 to get the percent. Therefore, as a percent is 65. A common mistake is to use the actual percentage increase/decrease rather than adding/subtracting from 100% . If you are told it is a 30% decrease, a common error would be to use 30% instead of 70% .Using reverse percentages is a way of working backwards on a percentages problem in order to find the original amount. In order to do this, we: Either add/subtract the percentage given in the problem from 100% to determine what percentage we have. Find 1% by dividing by percentage found in previous step.
