What is 398.5 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 7.25 is 100%, so we can write it down as 7.25=100%.
4. We know, that x is 398.5% of the output value, so we can write it down as x=398.5%.
5. Now we have two simple equations:
1) 7.25=100%
2) x=398.5%
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:
7.25/x=100%/398.5%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 398.5% of 7.25

7.25/x=100/398.5
(7.25/x)*x=(100/398.5)*x       - we multiply both sides of the equation by x
7.25=0.25094102885822*x       - we divide both sides of the equation by (0.25094102885822) to get x
7.25/0.25094102885822=x
28.89125=x
x=28.89125

now we have:
398.5% of 7.25=28.89125
