What is 398 percent of 502 - 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 502 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 502 is 100%, so we can write it down as 502=100%.
4. We know, that x is 398% of the output value, so we can write it down as x=398%.
5. Now we have two simple equations:
1) 502=100%
2) x=398%
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:
502/x=100%/398%
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% of 502

502/x=100/398
(502/x)*x=(100/398)*x       - we multiply both sides of the equation by x
502=0.25125628140704*x       - we divide both sides of the equation by (0.25125628140704) to get x
502/0.25125628140704=x
1997.96=x
x=1997.96

now we have:
398% of 502=1997.96
