What is 42 percent of 1287?
Answer: 540.54
Below you can find the procedure and formula used to arrive at the above answer.
Steps:
Lets assume 42 percent of 1287 is X.
Therefore, we can also say, X = 42% of 1287
42% can also be written as 42/100, because percent denotes a number per 100.
So, X = 42/100 × 1287
Or, X = 0.42 × 1287
So, X = 540.54
So, 42% of 1287 is 540.54
(You may also first multiply 42 with 1287, and then divide by 100 to find the answer, if that's easier for you.)

Now that we have calculated the answer, lets verify it using the percentage formula.
Answer verification
Percentage = Value/Total Value × 100
LHS (Percentage) = 42
RHS = 540.54/1287 × 100
Or, RHS = 0.42 × 100
So, RHS = 42
We can see that LHS = RHS, hence it's proved.
