215.15 is what percent of 603 - 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 603 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 603, so we can write it down as 100%=603.
4. We know, that x% equals 215.15 of the output value, so we can write it down as x%=215.15.
5. Now we have two simple equations:
1) 100%=603
2) x%=215.15
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%=603/215.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 215.15 is what percent of 603

100%/x%=603/215.15
(100/x)*x=(603/215.15)*x       - we multiply both sides of the equation by x
100=2.8026957936323*x       - we divide both sides of the equation by (2.8026957936323) to get x
100/2.8026957936323=x
35.679933665008=x
x=35.679933665008

now we have:
215.15 is 35.679933665008% of 603
