66.66 is what percent of 30 - 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 30 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 30, so we can write it down as 100%=30.
4. We know, that x% equals 66.66 of the output value, so we can write it down as x%=66.66.
5. Now we have two simple equations:
1) 100%=30
2) x%=66.66
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%=30/66.66
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 66.66 is what percent of 30

100%/x%=30/66.66
(100/x)*x=(30/66.66)*x       - we multiply both sides of the equation by x
100=0.45004500450045*x       - we divide both sides of the equation by (0.45004500450045) to get x
100/0.45004500450045=x
222.2=x
x=222.2

now we have:
66.66 is 222.2% of 30
