What is 40 percent of 680?
Answer: 272
Below you can find the procedure and formula used to arrive at the above answer.
Steps:
Lets assume 40 percent of 680 is X.
Therefore, we can also say, X = 40% of 680
40% can also be written as 40/100, because percent denotes a number per 100.
So, X = 40/100 × 680
Or, X = 0.4 × 680
So, X = 272
So, 40% of 680 is 272
(You may also first multiply 40 with 680, 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) = 40
RHS = 272/680 × 100
Or, RHS = 0.4 × 100
So, RHS = 40
We can see that LHS = RHS, hence it's proved.
