What is 4.45 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 4.45% of the output value, so we can write it down as x=4.45%.
5. Now we have two simple equations:
1) 857=100%
2) x=4.45%
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%/4.45%
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 4.45% of 857

857/x=100/4.45
(857/x)*x=(100/4.45)*x       - we multiply both sides of the equation by x
857=22.47191011236*x       - we divide both sides of the equation by (22.47191011236) to get x
857/22.47191011236=x
38.1365=x
x=38.1365

now we have:
4.45% of 857=38.1365
