6.34 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 6.34 of the output value, so we can write it down as x%=6.34.
5. Now we have two simple equations:
1) 100%=20
2) x%=6.34
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%=20/6.34
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.34 is what percent of 20

100%/x%=20/6.34
(100/x)*x=(20/6.34)*x       - we multiply both sides of the equation by x
100=3.1545741324921*x       - we divide both sides of the equation by (3.1545741324921) to get x
100/3.1545741324921=x
31.7=x
x=31.7

now we have:
6.34 is 31.7% of 20
