21.44 is what percent of 300 - 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 300 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 300, so we can write it down as 100%=300.
4. We know, that x% equals 21.44 of the output value, so we can write it down as x%=21.44.
5. Now we have two simple equations:
1) 100%=300
2) x%=21.44
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%=300/21.44
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.44 is what percent of 300

100%/x%=300/21.44
(100/x)*x=(300/21.44)*x       - we multiply both sides of the equation by x
100=13.992537313433*x       - we divide both sides of the equation by (13.992537313433) to get x
100/13.992537313433=x
7.1466666666667=x
x=7.1466666666667

now we have:
21.44 is 7.1466666666667% of 300
