What is 21.43 percent of 64 - 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 64 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 64 is 100%, so we can write it down as 64=100%.
4. We know, that x is 21.43% of the output value, so we can write it down as x=21.43%.
5. Now we have two simple equations:
1) 64=100%
2) x=21.43%
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:
64/x=100%/21.43%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 21.43% of 64

64/x=100/21.43
(64/x)*x=(100/21.43)*x       - we multiply both sides of the equation by x
64=4.6663555762949*x       - we divide both sides of the equation by (4.6663555762949) to get x
64/4.6663555762949=x
13.7152=x
x=13.7152

now we have:
21.43% of 64=13.7152
