0.25 is what percent of 3.14 - 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 3.14 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 3.14, so we can write it down as 100%=3.14.
4. We know, that x% equals 0.25 of the output value, so we can write it down as x%=0.25.
5. Now we have two simple equations:
1) 100%=3.14
2) x%=0.25
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%=3.14/0.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.25 is what percent of 3.14

100%/x%=3.14/0.25
(100/x)*x=(3.14/0.25)*x       - we multiply both sides of the equation by x
100=12.56*x       - we divide both sides of the equation by (12.56) to get x
100/12.56=x
7.9617834394904=x
x=7.9617834394904

now we have:
0.25 is 7.9617834394904% of 3.14
