What is 48.7 percent of 8.4 - 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 8.4 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 8.4 is 100%, so we can write it down as 8.4=100%.
4. We know, that x is 48.7% of the output value, so we can write it down as x=48.7%.
5. Now we have two simple equations:
1) 8.4=100%
2) x=48.7%
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:
8.4/x=100%/48.7%
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 48.7% of 8.4

8.4/x=100/48.7
(8.4/x)*x=(100/48.7)*x       - we multiply both sides of the equation by x
8.4=2.0533880903491*x       - we divide both sides of the equation by (2.0533880903491) to get x
8.4/2.0533880903491=x
4.0908=x
x=4.0908

now we have:
48.7% of 8.4=4.0908
