8.2 is what percent of 221.7 - 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 221.7 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 221.7, so we can write it down as 100%=221.7.
4. We know, that x% equals 8.2 of the output value, so we can write it down as x%=8.2.
5. Now we have two simple equations:
1) 100%=221.7
2) x%=8.2
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%=221.7/8.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.2 is what percent of 221.7

100%/x%=221.7/8.2
(100/x)*x=(221.7/8.2)*x       - we multiply both sides of the equation by x
100=27.036585365854*x       - we divide both sides of the equation by (27.036585365854) to get x
100/27.036585365854=x
3.6986919260262=x
x=3.6986919260262

now we have:
8.2 is 3.6986919260262% of 221.7
