What is 15 percent of 220000 - 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 220000 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 220000 is 100%, so we can write it down as 220000=100%.
4. We know, that x is 15% of the output value, so we can write it down as x=15%.
5. Now we have two simple equations:
1) 220000=100%
2) x=15%
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:
220000/x=100%/15%
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 15% of 220000

220000/x=100/15
(220000/x)*x=(100/15)*x       - we multiply both sides of the equation by x
220000=6.66666666667*x       - we divide both sides of the equation by (6.66666666667) to get x
220000/6.66666666667=x
33000=x
x=33000

now we have:
15% of 220000=33000
