64.12 is what percent of 84.4 - 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 84.4 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 84.4, so we can write it down as 100%=84.4.
4. We know, that x% equals 64.12 of the output value, so we can write it down as x%=64.12.
5. Now we have two simple equations:
1) 100%=84.4
2) x%=64.12
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%=84.4/64.12
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 64.12 is what percent of 84.4

100%/x%=84.4/64.12
(100/x)*x=(84.4/64.12)*x       - we multiply both sides of the equation by x
100=1.3162819713038*x       - we divide both sides of the equation by (1.3162819713038) to get x
100/1.3162819713038=x
75.971563981043=x
x=75.971563981043

now we have:
64.12 is 75.971563981043% of 84.4
