51 is what percent of 4590 - 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 4590 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 4590, so we can write it down as 100%=4590.
4. We know, that x% equals 51 of the output value, so we can write it down as x%=51.
5. Now we have two simple equations:
1) 100%=4590
2) x%=51
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%=4590/51
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 51 is what percent of 4590

100%/x%=4590/51
(100/x)*x=(4590/51)*x       - we multiply both sides of the equation by x
100=90*x       - we divide both sides of the equation by (90) to get x
100/90=x
1.1111111111111=x
x=1.1111111111111

now we have:
51 is 1.1111111111111% of 4590
