245.15 is what percent of 390.85 - 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 390.85 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 390.85, so we can write it down as 100%=390.85.
4. We know, that x% equals 245.15 of the output value, so we can write it down as x%=245.15.
5. Now we have two simple equations:
1) 100%=390.85
2) x%=245.15
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%=390.85/245.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 245.15 is what percent of 390.85

100%/x%=390.85/245.15
(100/x)*x=(390.85/245.15)*x       - we multiply both sides of the equation by x
100=1.5943300020396*x       - we divide both sides of the equation by (1.5943300020396) to get x
100/1.5943300020396=x
62.722271971345=x
x=62.722271971345

now we have:
245.15 is 62.722271971345% of 390.85
