45.8 is what percent of 78.5 - 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 78.5 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 78.5, so we can write it down as 100%=78.5.
4. We know, that x% equals 45.8 of the output value, so we can write it down as x%=45.8.
5. Now we have two simple equations:
1) 100%=78.5
2) x%=45.8
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%=78.5/45.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 45.8 is what percent of 78.5

100%/x%=78.5/45.8
(100/x)*x=(78.5/45.8)*x       - we multiply both sides of the equation by x
100=1.7139737991266*x       - we divide both sides of the equation by (1.7139737991266) to get x
100/1.7139737991266=x
58.343949044586=x
x=58.343949044586

now we have:
45.8 is 58.343949044586% of 78.5
