2.58 is what percent of 4.5 - 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 4.5 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 4.5, so we can write it down as 100%=4.5.
4. We know, that x% equals 2.58 of the output value, so we can write it down as x%=2.58.
5. Now we have two simple equations:
1) 100%=4.5
2) x%=2.58
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%=4.5/2.58
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.58 is what percent of 4.5

100%/x%=4.5/2.58
(100/x)*x=(4.5/2.58)*x       - we multiply both sides of the equation by x
100=1.7441860465116*x       - we divide both sides of the equation by (1.7441860465116) to get x
100/1.7441860465116=x
57.333333333333=x
x=57.333333333333

now we have:
2.58 is 57.333333333333% of 4.5
