0.39 is what percent of 5157 - 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 5157 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 5157, so we can write it down as 100%=5157.
4. We know, that x% equals 0.39 of the output value, so we can write it down as x%=0.39.
5. Now we have two simple equations:
1) 100%=5157
2) x%=0.39
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%=5157/0.39
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.39 is what percent of 5157

100%/x%=5157/0.39
(100/x)*x=(5157/0.39)*x       - we multiply both sides of the equation by x
100=13223.076923077*x       - we divide both sides of the equation by (13223.076923077) to get x
100/13223.076923077=x
0.0075625363583479=x
x=0.0075625363583479

now we have:
0.39 is 0.0075625363583479% of 5157
