What is 8.1 percent of 63 - 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 63 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 63 is 100%, so we can write it down as 63=100%.
4. We know, that x is 8.1% of the output value, so we can write it down as x=8.1%.
5. Now we have two simple equations:
1) 63=100%
2) x=8.1%
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:
63/x=100%/8.1%
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 8.1% of 63

63/x=100/8.1
(63/x)*x=(100/8.1)*x       - we multiply both sides of the equation by x
63=12.345679012346*x       - we divide both sides of the equation by (12.345679012346) to get x
63/12.345679012346=x
5.103=x
x=5.103

now we have:
8.1% of 63=5.103
