What is 90 percent of 580?
Answer: 522
Below you can find the procedure and formula used to arrive at the above answer.
Steps:
Lets assume 90 percent of 580 is X.
Therefore, we can also say, X = 90% of 580
90% can also be written as 90/100, because percent denotes a number per 100.
So, X = 90/100 × 580
Or, X = 0.9 × 580
So, X = 522
So, 90% of 580 is 522
(You may also first multiply 90 with 580, 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) = 90
RHS = 522/580 × 100
Or, RHS = 0.9 × 100
So, RHS = 90
We can see that LHS = RHS, hence it's proved.
