What is 8.3 percent of 615 - 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 615 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 615 is 100%, so we can write it down as 615=100%.
4. We know, that x is 8.3% of the output value, so we can write it down as x=8.3%.
5. Now we have two simple equations:
1) 615=100%
2) x=8.3%
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:
615/x=100%/8.3%
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 8.3% of 615

615/x=100/8.3
(615/x)*x=(100/8.3)*x       - we multiply both sides of the equation by x
615=12.048192771084*x       - we divide both sides of the equation by (12.048192771084) to get x
615/12.048192771084=x
51.045=x
x=51.045

now we have:
8.3% of 615=51.045
