28 is what percent of 3494 - 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 3494 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 3494, so we can write it down as 100%=3494.
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%=3494
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%=3494/28
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 3494

100%/x%=3494/28
(100/x)*x=(3494/28)*x       - we multiply both sides of the equation by x
100=124.78571428571*x       - we divide both sides of the equation by (124.78571428571) to get x
100/124.78571428571=x
0.80137378362908=x
x=0.80137378362908

now we have:
28 is 0.80137378362908% of 3494
