18720 is what percent of 4 - 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 4 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 4, so we can write it down as 100%=4.
4. We know, that x% equals 18720 of the output value, so we can write it down as x%=18720.
5. Now we have two simple equations:
1) 100%=4
2) x%=18720
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%=4/18720
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18720 is what percent of 4

100%/x%=4/18720
(100/x)*x=(4/18720)*x       - we multiply both sides of the equation by x
100=0.00021367521367521*x       - we divide both sides of the equation by (0.00021367521367521) to get x
100/0.00021367521367521=x
468000=x
x=468000

now we have:
18720 is 468000% of 4
