28 is what percent of 1916 - 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 1916 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 1916, so we can write it down as 100%=1916.
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%=1916
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%=1916/28
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 1916

100%/x%=1916/28
(100/x)*x=(1916/28)*x       - we multiply both sides of the equation by x
100=68.428571428571*x       - we divide both sides of the equation by (68.428571428571) to get x
100/68.428571428571=x
1.4613778705637=x
x=1.4613778705637

now we have:
28 is 1.4613778705637% of 1916
