81.53 is what percent of 700 - 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 700 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 700, so we can write it down as 100%=700.
4. We know, that x% equals 81.53 of the output value, so we can write it down as x%=81.53.
5. Now we have two simple equations:
1) 100%=700
2) x%=81.53
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%=700/81.53
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 81.53 is what percent of 700

100%/x%=700/81.53
(100/x)*x=(700/81.53)*x       - we multiply both sides of the equation by x
100=8.5857966392739*x       - we divide both sides of the equation by (8.5857966392739) to get x
100/8.5857966392739=x
11.647142857143=x
x=11.647142857143

now we have:
81.53 is 11.647142857143% of 700
