43.4 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 43.4 of the output value, so we can write it down as x%=43.4.
5. Now we have two simple equations:
1) 100%=51
2) x%=43.4
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%=51/43.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 43.4 is what percent of 51

100%/x%=51/43.4
(100/x)*x=(51/43.4)*x       - we multiply both sides of the equation by x
100=1.1751152073733*x       - we divide both sides of the equation by (1.1751152073733) to get x
100/1.1751152073733=x
85.098039215686=x
x=85.098039215686

now we have:
43.4 is 85.098039215686% of 51
