28 is what percent of 11900 - 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 11900 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 11900, so we can write it down as 100%=11900.
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%=11900
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%=11900/28
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 11900

100%/x%=11900/28
(100/x)*x=(11900/28)*x       - we multiply both sides of the equation by x
100=425*x       - we divide both sides of the equation by (425) to get x
100/425=x
0.23529411764706=x
x=0.23529411764706

now we have:
28 is 0.23529411764706% of 11900
