45 is what percent of 8.55 - 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 8.55 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 8.55, so we can write it down as 100%=8.55.
4. We know, that x% equals 45 of the output value, so we can write it down as x%=45.
5. Now we have two simple equations:
1) 100%=8.55
2) x%=45
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%=8.55/45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 45 is what percent of 8.55

100%/x%=8.55/45
(100/x)*x=(8.55/45)*x       - we multiply both sides of the equation by x
100=0.19*x       - we divide both sides of the equation by (0.19) to get x
100/0.19=x
526.31578947368=x
x=526.31578947368

now we have:
45 is 526.31578947368% of 8.55
