To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 379.99 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 100% equals 379.99, so we can write it down as 100%=379.99.
4. We know, that x% equals 247.99 of the output value, so we can write it down as x%=247.99.
5. Now we have two simple equations:
1) 100%=379.99
2) x%=247.99
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:
100%/x%=379.99/247.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 247.99 is what percent of 379.99

100%/x%=379.99/247.99
(100/x)*x=(379.99/247.99)*x       - we multiply both sides of the equation by x
100=1.5322795274003*x       - we divide both sides of the equation by (1.5322795274003) to get x
100/1.5322795274003=x
65.262243743256=x
x=65.262243743256

now we have:
