The simplest way to calculate percentage is to divide the given amount
by the total amount and then multiplying the answer by 100 to get the
percentage of the given amount with respect to the total amount.
The equation can be put up as follows:
(Given amount/ Total amount) x100
For example if John scores 60 out of 75 in mathematics we can find the
percentage of his marks by dividing 60 by 75 which comes to be 0.8 and
then multiplying it by 100 which gives us the percentage of his marks
in math which is 80%.
(60/75) x 100 = 80%
When there are a number of given amounts (variables) and we have to
find their individual percentages then we have to add the given amounts
to determine the total amount after which by the above mentioned
procedure we can easily find the individual percentages by dividing
each given amount by the total amount and then multiplying it by 100.
Percentage questions are often worded in different ways like how much
is x% of y (80% of 75). Using the above example we can find the answer
by multiplying 75 by 80 and then dividing the amount by 100 to find the
answer which is 60. To calculate percentage increase or decrease
between two numbers just subtract the smaller number from the greater
and then divide the answer by the original one and then multiply it by
100 to determine the percentage increase or decrease. For example to
calculate the percentage increase from 20 to 30 we subtract 20 from 30
and then divide the number obtained which is 10 by the original number
which is 20 and then multiply the obtained number which is 0.5 by 100
to get the percentage increase which is 50%.
