What is 8.7 percent of 3144 - 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 3144 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 3144 is 100%, so we can write it down as 3144=100%.
4. We know, that x is 8.7% of the output value, so we can write it down as x=8.7%.
5. Now we have two simple equations:
1) 3144=100%
2) x=8.7%
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:
3144/x=100%/8.7%
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 8.7% of 3144

3144/x=100/8.7
(3144/x)*x=(100/8.7)*x       - we multiply both sides of the equation by x
3144=11.494252873563*x       - we divide both sides of the equation by (11.494252873563) to get x
3144/11.494252873563=x
273.528=x
x=273.528

now we have:
8.7% of 3144=273.528
