What is 1500 percent of 398 - 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 398 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 398 is 100%, so we can write it down as 398=100%.
4. We know, that x is 1500% of the output value, so we can write it down as x=1500%.
5. Now we have two simple equations:
1) 398=100%
2) x=1500%
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:
398/x=100%/1500%
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 1500% of 398

398/x=100/1500
(398/x)*x=(100/1500)*x       - we multiply both sides of the equation by x
398=0.066666666666667*x       - we divide both sides of the equation by (0.066666666666667) to get x
398/0.066666666666667=x
5970=x
x=5970

now we have:
1500% of 398=5970
