What is 15.1 percent of 54.2 - 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 54.2 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 54.2 is 100%, so we can write it down as 54.2=100%.
4. We know, that x is 15.1% of the output value, so we can write it down as x=15.1%.
5. Now we have two simple equations:
1) 54.2=100%
2) x=15.1%
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:
54.2/x=100%/15.1%
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 15.1% of 54.2

54.2/x=100/15.1
(54.2/x)*x=(100/15.1)*x       - we multiply both sides of the equation by x
54.2=6.6225165562914*x       - we divide both sides of the equation by (6.6225165562914) to get x
54.2/6.6225165562914=x
8.1842=x
x=8.1842

now we have:
15.1% of 54.2=8.1842
