0.25 is what percent of 0.7 - 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 0.7 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 0.7, so we can write it down as 100%=0.7.
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%=0.7
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%=0.7/0.25
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 0.7

100%/x%=0.7/0.25
(100/x)*x=(0.7/0.25)*x       - we multiply both sides of the equation by x
100=2.8*x       - we divide both sides of the equation by (2.8) to get x
100/2.8=x
35.714285714286=x
x=35.714285714286

now we have:
0.25 is 35.714285714286% of 0.7
