What is 1.8 percent of 858 - 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 858 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 858 is 100%, so we can write it down as 858=100%.
4. We know, that x is 1.8% of the output value, so we can write it down as x=1.8%.
5. Now we have two simple equations:
1) 858=100%
2) x=1.8%
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:
858/x=100%/1.8%
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 1.8% of 858

858/x=100/1.8
(858/x)*x=(100/1.8)*x       - we multiply both sides of the equation by x
858=55.555555555556*x       - we divide both sides of the equation by (55.555555555556) to get x
858/55.555555555556=x
15.444=x
x=15.444

now we have:
1.8% of 858=15.444
