What is 67.8 percent of 23 - 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 23 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 23 is 100%, so we can write it down as 23=100%.
4. We know, that x is 67.8% of the output value, so we can write it down as x=67.8%.
5. Now we have two simple equations:
1) 23=100%
2) x=67.8%
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:
23/x=100%/67.8%
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 67.8% of 23

23/x=100/67.8
(23/x)*x=(100/67.8)*x       - we multiply both sides of the equation by x
23=1.4749262536873*x       - we divide both sides of the equation by (1.4749262536873) to get x
23/1.4749262536873=x
15.594=x
x=15.594

now we have:
67.8% of 23=15.594
