What is 0.8 percent of 871 - 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 871 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 871 is 100%, so we can write it down as 871=100%.
4. We know, that x is 0.8% of the output value, so we can write it down as x=0.8%.
5. Now we have two simple equations:
1) 871=100%
2) x=0.8%
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:
871/x=100%/0.8%
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 0.8% of 871

871/x=100/0.8
(871/x)*x=(100/0.8)*x       - we multiply both sides of the equation by x
871=125*x       - we divide both sides of the equation by (125) to get x
871/125=x
6.968=x
x=6.968

now we have:
0.8% of 871=6.968
