18.3 is what percent of 212 - 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 212 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 212, so we can write it down as 100%=212.
4. We know, that x% equals 18.3 of the output value, so we can write it down as x%=18.3.
5. Now we have two simple equations:
1) 100%=212
2) x%=18.3
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%=212/18.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.3 is what percent of 212

100%/x%=212/18.3
(100/x)*x=(212/18.3)*x       - we multiply both sides of the equation by x
100=11.584699453552*x       - we divide both sides of the equation by (11.584699453552) to get x
100/11.584699453552=x
8.6320754716981=x
x=8.6320754716981

now we have:
18.3 is 8.6320754716981% of 212
