What is 500 percent of 3.125 - 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 3.125 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 3.125 is 100%, so we can write it down as 3.125=100%.
4. We know, that x is 500% of the output value, so we can write it down as x=500%.
5. Now we have two simple equations:
1) 3.125=100%
2) x=500%
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:
3.125/x=100%/500%
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 500% of 3.125

3.125/x=100/500
(3.125/x)*x=(100/500)*x       - we multiply both sides of the equation by x
3.125=0.2*x       - we divide both sides of the equation by (0.2) to get x
3.125/0.2=x
15.625=x
x=15.625

now we have:
500% of 3.125=15.625
