22 is what percent of 490 - 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 490 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 490, so we can write it down as 100%=490.
4. We know, that x% equals 22 of the output value, so we can write it down as x%=22.
5. Now we have two simple equations:
1) 100%=490
2) x%=22
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%=490/22
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 22 is what percent of 490

100%/x%=490/22
(100/x)*x=(490/22)*x       - we multiply both sides of the equation by x
100=22.272727272727*x       - we divide both sides of the equation by (22.272727272727) to get x
100/22.272727272727=x
4.4897959183673=x
x=4.4897959183673

now we have:
22 is 4.4897959183673% of 490
