13.28 is what percent of 915.75 - 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 915.75 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 915.75, so we can write it down as 100%=915.75.
4. We know, that x% equals 13.28 of the output value, so we can write it down as x%=13.28.
5. Now we have two simple equations:
1) 100%=915.75
2) x%=13.28
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%=915.75/13.28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.28 is what percent of 915.75

100%/x%=915.75/13.28
(100/x)*x=(915.75/13.28)*x       - we multiply both sides of the equation by x
100=68.957078313253*x       - we divide both sides of the equation by (68.957078313253) to get x
100/68.957078313253=x
1.4501774501775=x
x=1.4501774501775

now we have:
13.28 is 1.4501774501775% of 915.75
