What is 1.78 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 1.78% of the output value, so we can write it down as x=1.78%.
5. Now we have two simple equations:
1) 871=100%
2) x=1.78%
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%/1.78%
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 1.78% of 871

871/x=100/1.78
(871/x)*x=(100/1.78)*x       - we multiply both sides of the equation by x
871=56.179775280899*x       - we divide both sides of the equation by (56.179775280899) to get x
871/56.179775280899=x
15.5038=x
x=15.5038

now we have:
1.78% of 871=15.5038
