0.31 is what percent of 20.47 - 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 20.47 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 20.47, so we can write it down as 100%=20.47.
4. We know, that x% equals 0.31 of the output value, so we can write it down as x%=0.31.
5. Now we have two simple equations:
1) 100%=20.47
2) x%=0.31
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%=20.47/0.31
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.31 is what percent of 20.47

100%/x%=20.47/0.31
(100/x)*x=(20.47/0.31)*x       - we multiply both sides of the equation by x
100=66.032258064516*x       - we divide both sides of the equation by (66.032258064516) to get x
100/66.032258064516=x
1.514411333659=x
x=1.514411333659

now we have:
0.31 is 1.514411333659% of 20.47
