What is 425 percent of 18.5 - 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 18.5 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 18.5 is 100%, so we can write it down as 18.5=100%.
4. We know, that x is 425% of the output value, so we can write it down as x=425%.
5. Now we have two simple equations:
1) 18.5=100%
2) x=425%
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:
18.5/x=100%/425%
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 425% of 18.5

18.5/x=100/425
(18.5/x)*x=(100/425)*x       - we multiply both sides of the equation by x
18.5=0.23529411764706*x       - we divide both sides of the equation by (0.23529411764706) to get x
18.5/0.23529411764706=x
78.625=x
x=78.625

now we have:
425% of 18.5=78.625
