90 is what percent of 2206 - 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 2206 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 2206, so we can write it down as 100%=2206.
4. We know, that x% equals 90 of the output value, so we can write it down as x%=90.
5. Now we have two simple equations:
1) 100%=2206
2) x%=90
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%=2206/90
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 90 is what percent of 2206

100%/x%=2206/90
(100/x)*x=(2206/90)*x       - we multiply both sides of the equation by x
100=24.511111111111*x       - we divide both sides of the equation by (24.511111111111) to get x
100/24.511111111111=x
4.0797824116047=x
x=4.0797824116047

now we have:
90 is 4.0797824116047% of 2206
