95% You simply subtract the decrease from the original 100%.
It is: (89-32.9)/89 times 100 = 63% decrease to the nearest whole number
12.5% (13%).
To calculate the percent increase, subtract the original value from the new value, then divide by the original value and multiply by 100. The calculation is: ((30.3 - 20.5) / 20.5 \times 100), which equals approximately (47.8%). Rounding to the nearest whole percent, the percent increase is (48%).
When a whole number is given- divide the percent given into the whole number and you will get the original number 39\40 should equal 97.5 great fun you should try it. Works every time.

When a whole number is given- divide the percent given into the whole number and you will get the original number 39\40 should equal 97.5 great fun you should try it. Works every time.
one whole as a percent = 100%
Part = Whole*Percent/100
25 percent of a whole = 25% of 100%
For example, a 10% decrease is equivalent to multiplying the original number by the factor 0.9. This is equal to (100-10)/100. In general, reducing something by a factor of "x" percent is equivalent to multiplying by a factor of (100-x)/100. Note that with some practice, you should be able to do all the calculations in your head, at least for a whole-number percentage.For an increase, change the minus to a plus - that's all.
Divide 265/250 = 1.06, which is 106 %. Since 100% is the whole original amount, the extra 6% is the increase over the original, so it is a 6% increase.
The whole is 100%
