What is 60 percent of 19.999 - 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 19.999 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 19.999 is 100%, so we can write it down as 19.999=100%.
4. We know, that x is 60% of the output value, so we can write it down as x=60%.
5. Now we have two simple equations:
1) 19.999=100%
2) x=60%
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:
19.999/x=100%/60%
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 60% of 19.999

19.999/x=100/60
(19.999/x)*x=(100/60)*x       - we multiply both sides of the equation by x
19.999=1.6666666666667*x       - we divide both sides of the equation by (1.6666666666667) to get x
19.999/1.6666666666667=x
11.9994=x
x=11.9994

now we have:
60% of 19.999=11.9994
