What is 0.219 percent of 0.25 - 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 0.25 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 0.25 is 100%, so we can write it down as 0.25=100%.
4. We know, that x is 0.219% of the output value, so we can write it down as x=0.219%.
5. Now we have two simple equations:
1) 0.25=100%
2) x=0.219%
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:
0.25/x=100%/0.219%
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 0.219% of 0.25

0.25/x=100/0.219
(0.25/x)*x=(100/0.219)*x       - we multiply both sides of the equation by x
0.25=456.62100456621*x       - we divide both sides of the equation by (456.62100456621) to get x
0.25/456.62100456621=x
0.0005475=x
x=0.0005475

now we have:
0.219% of 0.25=0.0005475
