28 is what percent of 2851 - 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 2851 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 2851, so we can write it down as 100%=2851.
4. We know, that x% equals 28 of the output value, so we can write it down as x%=28.
5. Now we have two simple equations:
1) 100%=2851
2) x%=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%=2851/28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 28 is what percent of 2851

100%/x%=2851/28
(100/x)*x=(2851/28)*x       - we multiply both sides of the equation by x
100=101.82142857143*x       - we divide both sides of the equation by (101.82142857143) to get x
100/101.82142857143=x
0.98211153981059=x
x=0.98211153981059

now we have:
28 is 0.98211153981059% of 2851
