What is 1.25 percent of 1721.25 - 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 1721.25 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 1721.25 is 100%, so we can write it down as 1721.25=100%.
4. We know, that x is 1.25% of the output value, so we can write it down as x=1.25%.
5. Now we have two simple equations:
1) 1721.25=100%
2) x=1.25%
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:
1721.25/x=100%/1.25%
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 1.25% of 1721.25

1721.25/x=100/1.25
(1721.25/x)*x=(100/1.25)*x       - we multiply both sides of the equation by x
1721.25=80*x       - we divide both sides of the equation by (80) to get x
1721.25/80=x
21.515625=x
x=21.515625

now we have:
1.25% of 1721.25=21.515625
