0.28 is what percent of 0.85 - 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 0.85 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 0.85, so we can write it down as 100%=0.85.
4. We know, that x% equals 0.28 of the output value, so we can write it down as x%=0.28.
5. Now we have two simple equations:
1) 100%=0.85
2) x%=0.28
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%=0.85/0.28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.28 is what percent of 0.85

100%/x%=0.85/0.28
(100/x)*x=(0.85/0.28)*x       - we multiply both sides of the equation by x
100=3.0357142857143*x       - we divide both sides of the equation by (3.0357142857143) to get x
100/3.0357142857143=x
32.941176470588=x
x=32.941176470588

now we have:
0.28 is 32.941176470588% of 0.85
