What is 21.04 percent of 6400 - 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 6400 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 6400 is 100%, so we can write it down as 6400=100%.
4. We know, that x is 21.04% of the output value, so we can write it down as x=21.04%.
5. Now we have two simple equations:
1) 6400=100%
2) x=21.04%
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:
6400/x=100%/21.04%
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 21.04% of 6400

6400/x=100/21.04
(6400/x)*x=(100/21.04)*x       - we multiply both sides of the equation by x
6400=4.7528517110266*x       - we divide both sides of the equation by (4.7528517110266) to get x
6400/4.7528517110266=x
1346.56=x
x=1346.56

now we have:
21.04% of 6400=1346.56
