What is 20.3 percent of 323.4 - 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 323.4 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 323.4 is 100%, so we can write it down as 323.4=100%.
4. We know, that x is 20.3% of the output value, so we can write it down as x=20.3%.
5. Now we have two simple equations:
1) 323.4=100%
2) x=20.3%
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:
323.4/x=100%/20.3%
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 20.3% of 323.4

323.4/x=100/20.3
(323.4/x)*x=(100/20.3)*x       - we multiply both sides of the equation by x
323.4=4.9261083743842*x       - we divide both sides of the equation by (4.9261083743842) to get x
323.4/4.9261083743842=x
65.6502=x
x=65.6502

now we have:
20.3% of 323.4=65.6502
