What is 4.55 percent of 312.5 - 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 312.5 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 312.5 is 100%, so we can write it down as 312.5=100%.
4. We know, that x is 4.55% of the output value, so we can write it down as x=4.55%.
5. Now we have two simple equations:
1) 312.5=100%
2) x=4.55%
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:
312.5/x=100%/4.55%
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 4.55% of 312.5

312.5/x=100/4.55
(312.5/x)*x=(100/4.55)*x       - we multiply both sides of the equation by x
312.5=21.978021978022*x       - we divide both sides of the equation by (21.978021978022) to get x
312.5/21.978021978022=x
14.21875=x
x=14.21875

now we have:
4.55% of 312.5=14.21875
