What is 15.8 percent of 50 - 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 50 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 50 is 100%, so we can write it down as 50=100%.
4. We know, that x is 15.8% of the output value, so we can write it down as x=15.8%.
5. Now we have two simple equations:
1) 50=100%
2) x=15.8%
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:
50/x=100%/15.8%
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 15.8% of 50

50/x=100/15.8
(50/x)*x=(100/15.8)*x       - we multiply both sides of the equation by x
50=6.3291139240506*x       - we divide both sides of the equation by (6.3291139240506) to get x
50/6.3291139240506=x
7.9=x
x=7.9

now we have:
15.8% of 50=7.9
