371 says 3% of 45.
7 is 1.
80 says 52 is 80% of 65.
Or 52 as a percent of 65 ends up being 80u2026%,52u00f7.
80 calculates what 52 is 80% of?,So 52u00f70.
80 = 65.
As long as you know percents as decimals, this should show the basics.

How to calculate percentage increase
Method #1Write down the starting value and the end value.
For example, lets say your auto insurance premium just went up.
Write down these values:,Your car insurance premium was $400 before the increase.
This is the starting value.
,After the increase, it costs $450.
This is the end value.
,Find the size of the increase.
Subtract the starting value from the end value to find the out how much it increased.
Were still working with ordinary numbers at this point, not percentages.
,In our example, $450 - $400 = a $50 increase.
,Divide the answer by the starting value.
A percentage is just a special kind of fraction.
For example, 5% of doctors is quick way to write 5 out of 100 doctors.
By dividing the answer by the starting value, we turn it into a fraction that compares the two values.
,In our example, $50 / $400 = 0.
,Multiply the result by 100.
This converts your last result into a percentage.
,The final answer to our example is 0.
125 x 100 = 12.
5% increase in auto insurance premiums.
,Method #2Write down the start value and end value.
Lets start with a new example.
The world population went from 5,300,000,00 people in 1990 to 7,400,000,000 in 2015.
,Theres a trick to these problems with many zeroes.
Instead of counting the zeroes each step of the way, we can rewrite these as 5.
3 billion and 7.
,Divide the end value by the starting value.
This will tell us how much bigger the end result is than the original.
4 billion u00f7 5.
3 billion = about 1.
,Weve rounded to two significant digits because thats how many there were in the original problem.
,Multiply by 100.
This will tell you the percentage comparison between the two values.
If the value increased (instead of decreasing), your answer should always be larger than 100.
4 x 100 = 140%.
This means the world population in 2015 is 140% the size of the population in 1990.
In this kind of problem, 100% is the size of the starting value.
By subtracting this from our answer, were left with just the percentage size of the increase.
,140% - 100% = a 40% increase in population.
,This works because starting value + increase = end value.
Rearrange the equation and we get increase = end value - starting value
Percentage difference calculator
Suppose an item costs $40.
And then its price was marked up to $50.
What per cent mark up was this?,The way to figure this, is to first calculate how much the markup was.
Here is is 50 - 40 = $10.
,Then divide this by the original cost: 10/40 = 25% increase.
,So in general if an item costs C dollars and is increased (or decreased) to D dollars, the per cent increase is 100% * (D - C) / C.
,----,Its interesting, and confusing to many people to see the result you get if you reverse this process.
,Suppose an item costs $50 and its price was marked down to $40.
,This looks like the opposite of the original problem above, so one might think the answer is a 25% decrease.
But it isnt.
,If we apply the formula I gave above, we get 100% * ( 40 - 50) / 50 = -20%.
,So the per cent drop from $50 to $40 is 20%, but the percent increase from $40 to $50 is 25%.
,-----,This sort of question is one that I get often from my friends because it is not intuitively obvious.
Such is life.
