23.1 is what percent of 51 - 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 51 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 51, so we can write it down as 100%=51.
4. We know, that x% equals 23.1 of the output value, so we can write it down as x%=23.1.
5. Now we have two simple equations:
1) 100%=51
2) x%=23.1
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%=51/23.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 23.1 is what percent of 51

100%/x%=51/23.1
(100/x)*x=(51/23.1)*x       - we multiply both sides of the equation by x
100=2.2077922077922*x       - we divide both sides of the equation by (2.2077922077922) to get x
100/2.2077922077922=x
45.294117647059=x
x=45.294117647059

now we have:
23.1 is 45.294117647059% of 51
