What is 31.5 percent of 68000 - 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 68000 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 68000 is 100%, so we can write it down as 68000=100%.
4. We know, that x is 31.5% of the output value, so we can write it down as x=31.5%.
5. Now we have two simple equations:
1) 68000=100%
2) x=31.5%
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:
68000/x=100%/31.5%
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 31.5% of 68000

68000/x=100/31.5
(68000/x)*x=(100/31.5)*x       - we multiply both sides of the equation by x
68000=3.1746031746032*x       - we divide both sides of the equation by (3.1746031746032) to get x
68000/3.1746031746032=x
21420=x
x=21420

now we have:
31.5% of 68000=21420
