What is 1.25 percent of 987.5 - 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 987.5 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 987.5 is 100%, so we can write it down as 987.5=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) 987.5=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:
987.5/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 987.5

987.5/x=100/1.25
(987.5/x)*x=(100/1.25)*x       - we multiply both sides of the equation by x
987.5=80*x       - we divide both sides of the equation by (80) to get x
987.5/80=x
12.34375=x
x=12.34375

now we have:
1.25% of 987.5=12.34375
