54.21 is what percent of 1085.16 - 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 1085.16 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 1085.16, so we can write it down as 100%=1085.16.
4. We know, that x% equals 54.21 of the output value, so we can write it down as x%=54.21.
5. Now we have two simple equations:
1) 100%=1085.16
2) x%=54.21
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%=1085.16/54.21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 54.21 is what percent of 1085.16

100%/x%=1085.16/54.21
(100/x)*x=(1085.16/54.21)*x       - we multiply both sides of the equation by x
100=20.017708909795*x       - we divide both sides of the equation by (20.017708909795) to get x
100/20.017708909795=x
4.9955766891518=x
x=4.9955766891518

now we have:
54.21 is 4.9955766891518% of 1085.16
