4 is what percent of 18.65 - 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 18.65 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 18.65, so we can write it down as 100%=18.65.
4. We know, that x% equals 4 of the output value, so we can write it down as x%=4.
5. Now we have two simple equations:
1) 100%=18.65
2) x%=4
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%=18.65/4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4 is what percent of 18.65

100%/x%=18.65/4
(100/x)*x=(18.65/4)*x       - we multiply both sides of the equation by x
100=4.6625*x       - we divide both sides of the equation by (4.6625) to get x
100/4.6625=x
21.447721179625=x
x=21.447721179625

now we have:
4 is 21.447721179625% of 18.65
