What is 1.8 percent of 47.5 - 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 47.5 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 47.5 is 100%, so we can write it down as 47.5=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) 47.5=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:
47.5/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 47.5

47.5/x=100/1.8
(47.5/x)*x=(100/1.8)*x       - we multiply both sides of the equation by x
47.5=55.555555555556*x       - we divide both sides of the equation by (55.555555555556) to get x
47.5/55.555555555556=x
0.855=x
x=0.855

now we have:
1.8% of 47.5=0.855
