What is 77 percent of 509?
Answer: 391.93
Below you can find the procedure and formula used to arrive at the above answer.
Steps:
Lets assume 77 percent of 509 is X.
Therefore, we can also say, X = 77% of 509
77% can also be written as 77/100, because percent denotes a number per 100.
So, X = 77/100 × 509
Or, X = 0.77 × 509
So, X = 391.93

Now that we have calculated the answer, lets verify it using the percentage formula.
Answer verification
Percentage = Value/Total Value × 100
LHS (Percentage) = 77
RHS = 391.93/509 × 100
Or, RHS = 0.77 × 100
So, RHS = 77
We can see that LHS = RHS, hence it's proved.
