86.71 is what percent of 289.35 - 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 289.35 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 289.35, so we can write it down as 100%=289.35.
4. We know, that x% equals 86.71 of the output value, so we can write it down as x%=86.71.
5. Now we have two simple equations:
1) 100%=289.35
2) x%=86.71
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%=289.35/86.71
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 86.71 is what percent of 289.35

100%/x%=289.35/86.71
(100/x)*x=(289.35/86.71)*x       - we multiply both sides of the equation by x
100=3.3369853534771*x       - we divide both sides of the equation by (3.3369853534771) to get x
100/3.3369853534771=x
29.967167789874=x
x=29.967167789874

now we have:
