What is 10 percent of 644?
Answer: 64.4
Below you can find the procedure and formula used to arrive at the above answer.
Steps:
Lets assume 10 percent of 644 is X.
Therefore, we can also say, X = 10% of 644
10% can also be written as 10/100, because percent denotes a number per 100.
So, X = 10/100 × 644
Or, X = 0.1 × 644
So, X = 64.4
So, 10% of 644 is 64.4
(You may also first multiply 10 with 644, 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) = 10
RHS = 64.4/644 × 100
Or, RHS = 0.1 × 100
So, RHS = 10
We can see that LHS = RHS, hence it's proved.
