2.21 is what percent of 7.25 - 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 7.25 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 7.25, so we can write it down as 100%=7.25.
4. We know, that x% equals 2.21 of the output value, so we can write it down as x%=2.21.
5. Now we have two simple equations:
1) 100%=7.25
2) x%=2.21
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%=7.25/2.21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.21 is what percent of 7.25

100%/x%=7.25/2.21
(100/x)*x=(7.25/2.21)*x       - we multiply both sides of the equation by x
100=3.2805429864253*x       - we divide both sides of the equation by (3.2805429864253) to get x
100/3.2805429864253=x
30.48275862069=x
x=30.48275862069

now we have:
2.21 is 30.48275862069% of 7.25
