36.9 is what percent of 51.6 - 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 51.6 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 51.6, so we can write it down as 100%=51.6.
4. We know, that x% equals 36.9 of the output value, so we can write it down as x%=36.9.
5. Now we have two simple equations:
1) 100%=51.6
2) x%=36.9
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%=51.6/36.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 36.9 is what percent of 51.6

100%/x%=51.6/36.9
(100/x)*x=(51.6/36.9)*x       - we multiply both sides of the equation by x
100=1.3983739837398*x       - we divide both sides of the equation by (1.3983739837398) to get x
100/1.3983739837398=x
71.511627906977=x
x=71.511627906977

now we have:
36.9 is 71.511627906977% of 51.6
