12.84 is what percent of 206.4 - 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 206.4 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 206.4, so we can write it down as 100%=206.4.
4. We know, that x% equals 12.84 of the output value, so we can write it down as x%=12.84.
5. Now we have two simple equations:
1) 100%=206.4
2) x%=12.84
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%=206.4/12.84
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.84 is what percent of 206.4

100%/x%=206.4/12.84
(100/x)*x=(206.4/12.84)*x       - we multiply both sides of the equation by x
100=16.07476635514*x       - we divide both sides of the equation by (16.07476635514) to get x
100/16.07476635514=x
6.2209302325581=x
x=6.2209302325581

now we have:
12.84 is 6.2209302325581% of 206.4
