4.86 is what percent of 20 - 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 20 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 20, so we can write it down as 100%=20.
4. We know, that x% equals 4.86 of the output value, so we can write it down as x%=4.86.
5. Now we have two simple equations:
1) 100%=20
2) x%=4.86
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%=20/4.86
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.86 is what percent of 20

100%/x%=20/4.86
(100/x)*x=(20/4.86)*x       - we multiply both sides of the equation by x
100=4.1152263374486*x       - we divide both sides of the equation by (4.1152263374486) to get x
100/4.1152263374486=x
24.3=x
x=24.3

now we have:
4.86 is 24.3% of 20
