31.32 is what percent of 2119.78 - 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 2119.78 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 2119.78, so we can write it down as 100%=2119.78.
4. We know, that x% equals 31.32 of the output value, so we can write it down as x%=31.32.
5. Now we have two simple equations:
1) 100%=2119.78
2) x%=31.32
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%=2119.78/31.32
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31.32 is what percent of 2119.78

100%/x%=2119.78/31.32
(100/x)*x=(2119.78/31.32)*x       - we multiply both sides of the equation by x
100=67.681353767561*x       - we divide both sides of the equation by (67.681353767561) to get x
100/67.681353767561=x
1.4775118172641=x
x=1.4775118172641

now we have:
