21.16 is what percent of 1200 - 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 1200 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 1200, so we can write it down as 100%=1200.
4. We know, that x% equals 21.16 of the output value, so we can write it down as x%=21.16.
5. Now we have two simple equations:
1) 100%=1200
2) x%=21.16
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%=1200/21.16
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.16 is what percent of 1200

100%/x%=1200/21.16
(100/x)*x=(1200/21.16)*x       - we multiply both sides of the equation by x
100=56.710775047259*x       - we divide both sides of the equation by (56.710775047259) to get x
100/56.710775047259=x
1.7633333333333=x
x=1.7633333333333

now we have:
21.16 is 1.7633333333333% of 1200
