1388.4 is what percent of 9720.15 - 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 9720.15 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 9720.15, so we can write it down as 100%=9720.15.
4. We know, that x% equals 1388.4 of the output value, so we can write it down as x%=1388.4.
5. Now we have two simple equations:
1) 100%=9720.15
2) x%=1388.4
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%=9720.15/1388.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1388.4 is what percent of 9720.15

100%/x%=9720.15/1388.4
(100/x)*x=(9720.15/1388.4)*x       - we multiply both sides of the equation by x
100=7.0009723422645*x       - we divide both sides of the equation by (7.0009723422645) to get x
100/7.0009723422645=x
14.283730189349=x
x=14.283730189349

now we have:
1388.4 is 14.283730189349% of 9720.15
