What is 7.65 percent of 402 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 402 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 402 is 100%, so we can write it down as 402=100%.
4. We know, that x is 7.65% of the output value, so we can write it down as x=7.65%.
5. Now we have two simple equations:
1) 402=100%
2) x=7.65%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
402/x=100%/7.65%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 7.65% of 402

402/x=100/7.65
(402/x)*x=(100/7.65)*x       - we multiply both sides of the equation by x
402=13.071895424837*x       - we divide both sides of the equation by (13.071895424837) to get x
402/13.071895424837=x
30.753=x
x=30.753

now we have:
7.65% of 402=30.753
