What is 399.99 percent of 329.99 - 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 329.99 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 329.99 is 100%, so we can write it down as 329.99=100%.
4. We know, that x is 399.99% of the output value, so we can write it down as x=399.99%.
5. Now we have two simple equations:
1) 329.99=100%
2) x=399.99%
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:
329.99/x=100%/399.99%
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 399.99% of 329.99

329.99/x=100/399.99
(329.99/x)*x=(100/399.99)*x       - we multiply both sides of the equation by x
329.99=0.25000625015625*x       - we divide both sides of the equation by (0.25000625015625) to get x
329.99/0.25000625015625=x
1319.927001=x
x=1319.927001

now we have:
399.99% of 329.99=1319.927001
