89 is what percent of 722 - 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 722 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 722, so we can write it down as 100%=722.
4. We know, that x% equals 89 of the output value, so we can write it down as x%=89.
5. Now we have two simple equations:
1) 100%=722
2) x%=89
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%=722/89
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 89 is what percent of 722

100%/x%=722/89
(100/x)*x=(722/89)*x       - we multiply both sides of the equation by x
100=8.1123595505618*x       - we divide both sides of the equation by (8.1123595505618) to get x
100/8.1123595505618=x
12.326869806094=x
x=12.326869806094

now we have:
89 is 12.326869806094% of 722
