What is 20 percent of 215175 - 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 215175 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 215175 is 100%, so we can write it down as 215175=100%.
4. We know, that x is 20% of the output value, so we can write it down as x=20%.
5. Now we have two simple equations:
1) 215175=100%
2) x=20%
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:
215175/x=100%/20%
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% of 215175

215175/x=100/20
(215175/x)*x=(100/20)*x       - we multiply both sides of the equation by x
215175=5*x       - we divide both sides of the equation by (5) to get x
215175/5=x
43035=x
x=43035

now we have:
20% of 215175=43035
