28 is what percent of 2289 - 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 2289 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 2289, so we can write it down as 100%=2289.
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%=2289
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%=2289/28
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 2289

100%/x%=2289/28
(100/x)*x=(2289/28)*x       - we multiply both sides of the equation by x
100=81.75*x       - we divide both sides of the equation by (81.75) to get x
100/81.75=x
1.2232415902141=x
x=1.2232415902141

now we have:
28 is 1.2232415902141% of 2289
