9.75 is what percent of 215 - 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 215 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 215, so we can write it down as 100%=215.
4. We know, that x% equals 9.75 of the output value, so we can write it down as x%=9.75.
5. Now we have two simple equations:
1) 100%=215
2) x%=9.75
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%=215/9.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9.75 is what percent of 215

100%/x%=215/9.75
(100/x)*x=(215/9.75)*x       - we multiply both sides of the equation by x
100=22.051282051282*x       - we divide both sides of the equation by (22.051282051282) to get x
100/22.051282051282=x
4.5348837209302=x
x=4.5348837209302

now we have:
9.75 is 4.5348837209302% of 215
