28 is what percent of 442 - 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 442 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 442, so we can write it down as 100%=442.
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%=442
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%=442/28
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 442

100%/x%=442/28
(100/x)*x=(442/28)*x       - we multiply both sides of the equation by x
100=15.785714285714*x       - we divide both sides of the equation by (15.785714285714) to get x
100/15.785714285714=x
6.3348416289593=x
x=6.3348416289593

now we have:
28 is 6.3348416289593% of 442
