Step 1There are 2 ways of writing percent, both of which mean the same thing. They just look different.Example: Suppose we had sixty percent. This can be written as60% or 60100The ward part of &#039;per&#039; in percent means &#039;for each of&#039;.The word part of &#039;cent&#039; in percent means 100. Think of century which is 100 years.Step 2The level of increase is 15−10=5, but this is part of the total original count of ten. So the change as a fraction is :15−1010=510To change this to percentage we change the bottom number (denominator) to 100.What we do to the top we do to the bottomMultiply by 1 but in the form of 1=1010510×1→510×1010=50100So the increase is 50100→50%
