21.8 is what percent of 1206 - 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 1206 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 1206, so we can write it down as 100%=1206.
4. We know, that x% equals 21.8 of the output value, so we can write it down as x%=21.8.
5. Now we have two simple equations:
1) 100%=1206
2) x%=21.8
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%=1206/21.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.8 is what percent of 1206

100%/x%=1206/21.8
(100/x)*x=(1206/21.8)*x       - we multiply both sides of the equation by x
100=55.321100917431*x       - we divide both sides of the equation by (55.321100917431) to get x
100/55.321100917431=x
1.8076285240464=x
x=1.8076285240464

now we have:
21.8 is 1.8076285240464% of 1206
