2.2 is what percent of 99.8 - 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 99.8 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 99.8, so we can write it down as 100%=99.8.
4. We know, that x% equals 2.2 of the output value, so we can write it down as x%=2.2.
5. Now we have two simple equations:
1) 100%=99.8
2) x%=2.2
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%=99.8/2.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.2 is what percent of 99.8

100%/x%=99.8/2.2
(100/x)*x=(99.8/2.2)*x       - we multiply both sides of the equation by x
100=45.363636363636*x       - we divide both sides of the equation by (45.363636363636) to get x
100/45.363636363636=x
2.2044088176353=x
x=2.2044088176353

now we have:
2.2 is 2.2044088176353% of 99.8
