99 is what percent of 422 - 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 422 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 422, so we can write it down as 100%=422.
4. We know, that x% equals 99 of the output value, so we can write it down as x%=99.
5. Now we have two simple equations:
1) 100%=422
2) x%=99
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%=422/99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 99 is what percent of 422

100%/x%=422/99
(100/x)*x=(422/99)*x       - we multiply both sides of the equation by x
100=4.2626262626263*x       - we divide both sides of the equation by (4.2626262626263) to get x
100/4.2626262626263=x
23.45971563981=x
x=23.45971563981

now we have:
99 is 23.45971563981% of 422
