962.5 is what percent of 1215 - 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 1215 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 1215, so we can write it down as 100%=1215.
4. We know, that x% equals 962.5 of the output value, so we can write it down as x%=962.5.
5. Now we have two simple equations:
1) 100%=1215
2) x%=962.5
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%=1215/962.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 962.5 is what percent of 1215

100%/x%=1215/962.5
(100/x)*x=(1215/962.5)*x       - we multiply both sides of the equation by x
100=1.2623376623377*x       - we divide both sides of the equation by (1.2623376623377) to get x
100/1.2623376623377=x
79.218106995885=x
x=79.218106995885

now we have:
962.5 is 79.218106995885% of 1215
