9.75 is what percent of 21.25 - 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 21.25 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 21.25, so we can write it down as 100%=21.25.
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%=21.25
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%=21.25/9.75
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 21.25

100%/x%=21.25/9.75
(100/x)*x=(21.25/9.75)*x       - we multiply both sides of the equation by x
100=2.1794871794872*x       - we divide both sides of the equation by (2.1794871794872) to get x
100/2.1794871794872=x
45.882352941176=x
x=45.882352941176

now we have:
9.75 is 45.882352941176% of 21.25
