What is 1225 percent of 8.7 - 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 8.7 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 8.7 is 100%, so we can write it down as 8.7=100%.
4. We know, that x is 1225% of the output value, so we can write it down as x=1225%.
5. Now we have two simple equations:
1) 8.7=100%
2) x=1225%
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:
8.7/x=100%/1225%
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 1225% of 8.7

8.7/x=100/1225
(8.7/x)*x=(100/1225)*x       - we multiply both sides of the equation by x
8.7=0.081632653061224*x       - we divide both sides of the equation by (0.081632653061224) to get x
8.7/0.081632653061224=x
106.575=x
x=106.575

now we have:
1225% of 8.7=106.575
