What is 20 percent of 815?
Answer: 163
Below you can find the procedure and formula used to arrive at the above answer.
Steps:
Lets assume 20 percent of 815 is X.
Therefore, we can also say, X = 20% of 815
20% can also be written as 20/100, because percent denotes a number per 100.
So, X = 20/100 × 815
Or, X = 0.2 × 815
So, X = 163
So, 20% of 815 is 163
(You may also first multiply 20 with 815, and then divide by 100 to find the answer, if that's easier for you.)
% of
=
Now that we have calculated the answer, lets verify it using the percentage formula.
Answer verification
Percentage = Value/Total Value × 100
LHS (Percentage) = 20
RHS = 163/815 × 100
Or, RHS = 0.2 × 100
So, RHS = 20
We can see that LHS = RHS, hence it's proved.
