What is 4 percent of 1280?
Answer: 51.2
Below you can find the procedure and formula used to arrive at the above answer.
Steps:
Lets assume 4 percent of 1280 is X.
Therefore, we can also say, X = 4% of 1280
4% can also be written as 4/100, because percent denotes a number per 100.
So, X = 4/100 × 1280
Or, X = 0.04 × 1280
So, X = 51.2
So, 4% of 1280 is 51.2
(You may also first multiply 4 with 1280, 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) = 4
RHS = 51.2/1280 × 100
Or, RHS = 0.04 × 100
So, RHS = 4
We can see that LHS = RHS, hence it's proved.
