516.8 is what percent of 1300 - 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 1300 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 1300, so we can write it down as 100%=1300.
4. We know, that x% equals 516.8 of the output value, so we can write it down as x%=516.8.
5. Now we have two simple equations:
1) 100%=1300
2) x%=516.8
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%=1300/516.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 516.8 is what percent of 1300

100%/x%=1300/516.8
(100/x)*x=(1300/516.8)*x       - we multiply both sides of the equation by x
100=2.515479876161*x       - we divide both sides of the equation by (2.515479876161) to get x
100/2.515479876161=x
39.753846153846=x
x=39.753846153846

now we have:
516.8 is 39.753846153846% of 1300
