What is 80.6 percent of 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 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 5 is 100%, so we can write it down as 5=100%.
4. We know, that x is 80.6% of the output value, so we can write it down as x=80.6%.
5. Now we have two simple equations:
1) 5=100%
2) x=80.6%
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:
5/x=100%/80.6%
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 80.6% of 5

5/x=100/80.6
(5/x)*x=(100/80.6)*x       - we multiply both sides of the equation by x
5=1.2406947890819*x       - we divide both sides of the equation by (1.2406947890819) to get x
5/1.2406947890819=x
4.03=x
x=4.03

now we have:
80.6% of 5=4.03
