What is 119.99 percent of 399.5 - 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 399.5 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 399.5 is 100%, so we can write it down as 399.5=100%.
4. We know, that x is 119.99% of the output value, so we can write it down as x=119.99%.
5. Now we have two simple equations:
1) 399.5=100%
2) x=119.99%
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:
399.5/x=100%/119.99%
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 119.99% of 399.5

399.5/x=100/119.99
(399.5/x)*x=(100/119.99)*x       - we multiply both sides of the equation by x
399.5=0.8334027835653*x       - we divide both sides of the equation by (0.8334027835653) to get x
399.5/0.8334027835653=x
479.36005=x
x=479.36005

now we have:
119.99% of 399.5=479.36005
