3.95 is what percent of 19.43 - 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 19.43 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 19.43, so we can write it down as 100%=19.43.
4. We know, that x% equals 3.95 of the output value, so we can write it down as x%=3.95.
5. Now we have two simple equations:
1) 100%=19.43
2) x%=3.95
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%=19.43/3.95
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.95 is what percent of 19.43

100%/x%=19.43/3.95
(100/x)*x=(19.43/3.95)*x       - we multiply both sides of the equation by x
100=4.9189873417722*x       - we divide both sides of the equation by (4.9189873417722) to get x
100/4.9189873417722=x
20.329387545033=x
x=20.329387545033

now we have:
3.95 is 20.329387545033% of 19.43
