78333333.33 is what percent of 400000000 - 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 400000000 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 400000000, so we can write it down as 100%=400000000.
4. We know, that x% equals 78333333.33 of the output value, so we can write it down as x%=78333333.33.
5. Now we have two simple equations:
1) 100%=400000000
2) x%=78333333.33
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%=400000000/78333333.33
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 78333333.33 is what percent of 400000000
