What is 3.87 percent of 857 - 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 857 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 857 is 100%, so we can write it down as 857=100%.
4. We know, that x is 3.87% of the output value, so we can write it down as x=3.87%.
5. Now we have two simple equations:
1) 857=100%
2) x=3.87%
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:
857/x=100%/3.87%
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 3.87% of 857

857/x=100/3.87
(857/x)*x=(100/3.87)*x       - we multiply both sides of the equation by x
857=25.839793281654*x       - we divide both sides of the equation by (25.839793281654) to get x
857/25.839793281654=x
33.1659=x
x=33.1659

now we have:
3.87% of 857=33.1659
