11.3 is what percent of 315 - 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 315 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 100% equals 315, so we can write it down as 100%=315.
4. We know, that x% equals 11.3 of the output value, so we can write it down as x%=11.3.
5. Now we have two simple equations:
1) 100%=315
2) x%=11.3
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:
100%/x%=315/11.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 11.3 is what percent of 315

100%/x%=315/11.3
(100/x)*x=(315/11.3)*x       - we multiply both sides of the equation by x
100=27.87610619469*x       - we divide both sides of the equation by (27.87610619469) to get x
100/27.87610619469=x
3.5873015873016=x
x=3.5873015873016

now we have:
11.3 is 3.5873015873016% of 315
