22 is what percent of 691 - 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 691 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 691, so we can write it down as 100%=691.
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%=691
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%=691/22
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 691

100%/x%=691/22
(100/x)*x=(691/22)*x       - we multiply both sides of the equation by x
100=31.409090909091*x       - we divide both sides of the equation by (31.409090909091) to get x
100/31.409090909091=x
3.1837916063676=x
x=3.1837916063676

now we have:
22 is 3.1837916063676% of 691
