4.47 is what percent of 8.5 - 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 8.5 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 8.5, so we can write it down as 100%=8.5.
4. We know, that x% equals 4.47 of the output value, so we can write it down as x%=4.47.
5. Now we have two simple equations:
1) 100%=8.5
2) x%=4.47
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%=8.5/4.47
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.47 is what percent of 8.5

100%/x%=8.5/4.47
(100/x)*x=(8.5/4.47)*x       - we multiply both sides of the equation by x
100=1.9015659955257*x       - we divide both sides of the equation by (1.9015659955257) to get x
100/1.9015659955257=x
52.588235294118=x
x=52.588235294118

now we have:
4.47 is 52.588235294118% of 8.5
