253.22 is what percent of 318 - 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 318 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 318, so we can write it down as 100%=318.
4. We know, that x% equals 253.22 of the output value, so we can write it down as x%=253.22.
5. Now we have two simple equations:
1) 100%=318
2) x%=253.22
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%=318/253.22
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 253.22 is what percent of 318

100%/x%=318/253.22
(100/x)*x=(318/253.22)*x       - we multiply both sides of the equation by x
100=1.2558249743306*x       - we divide both sides of the equation by (1.2558249743306) to get x
100/1.2558249743306=x
79.62893081761=x
x=79.62893081761

now we have:
253.22 is 79.62893081761% of 318
