What is 104.5 percent of 398.7 - 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 398.7 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 398.7 is 100%, so we can write it down as 398.7=100%.
4. We know, that x is 104.5% of the output value, so we can write it down as x=104.5%.
5. Now we have two simple equations:
1) 398.7=100%
2) x=104.5%
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:
398.7/x=100%/104.5%
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 104.5% of 398.7

398.7/x=100/104.5
(398.7/x)*x=(100/104.5)*x       - we multiply both sides of the equation by x
398.7=0.95693779904306*x       - we divide both sides of the equation by (0.95693779904306) to get x
398.7/0.95693779904306=x
416.6415=x
x=416.6415

now we have:
104.5% of 398.7=416.6415
