You would multiply the amount by 1.27 in order to end up with the whole amount (the one) plus .27 of that amount (the .27). See below, and see Discussion for a little more information on why this works.
_______
To put the above in slightly different words as a secondary explanation:
This is because increasing by 27 percent means you are calculating 127% of the original. 127% means 127 per 100 which as a fraction is written as 127/100.
This equals 1.27.
27 out of 45 (or 27/45) = 0.6To convert 0.6 to percent multiply by 100: 0.6 × 100 = 60 %
3.8571
Multiply it by 0.30 and get 27
You multiply the amount of minutes by the amount of seconds in a minute. 27*60 The answer is 1620
27
12.5% increase
50% increase.
To convert a decimal to a percent, multiply by 100: 27 x 100 = 270%
Multiply it by 100 and so it is 27%
8 x 100/27 = 30%
27 out of 45 (or 27/45) = 0.6To convert 0.6 to percent multiply by 100: 0.6 × 100 = 60 %
3.8571
125%
27 to 72 is an increase of 166.67%
Multiply it by 0.30 and get 27
First you take the difference between the numbers (45 - 18 = 27). Then take that number and divide it by the original number. So 27/18 = 1.5 Then multiply by 100 for the percent. 1.5 x 100 = 150%.
To find 27 percent of a number, multiply the number by 0.27. In this instance, 0.27 x 55 = 14.85. Therefore, 27 percent of 55 is equal to 14.85.
