What is 31 percent of 1290?
Answer: 399.9
Below you can find the procedure and formula used to arrive at the above answer.
Steps:
Lets assume 31 percent of 1290 is X.
Therefore, we can also say, X = 31% of 1290
31% can also be written as 31/100, because percent denotes a number per 100.
So, X = 31/100 × 1290
Or, X = 0.31 × 1290
So, X = 399.9
So, 31% of 1290 is 399.9
(You may also first multiply 31 with 1290, 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) = 31
RHS = 399.9/1290 × 100
Or, RHS = 0.31 × 100
So, RHS = 31
We can see that LHS = RHS, hence it's proved.
