What is 64.3 percent of 20000000 - 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 20000000 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 20000000 is 100%, so we can write it down as 20000000=100%.
4. We know, that x is 64.3% of the output value, so we can write it down as x=64.3%.
5. Now we have two simple equations:
1) 20000000=100%
2) x=64.3%
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:
20000000/x=100%/64.3%
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 64.3% of 20000000

20000000/x=100/64.3
(20000000/x)*x=(100/64.3)*x       - we multiply both sides of the equation by x
20000000=1.5552099533437*x       - we divide both sides of the equation by (1.5552099533437) to get x
20000000/1.5552099533437=x
12860000=x
x=12860000

now we have:
64.3% of 20000000=12860000
