80 is what percent of 14.2 - 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 14.2 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 100% equals 14.2, so we can write it down as 100%=14.2.
4. We know, that x% equals 80 of the output value, so we can write it down as x%=80.
5. Now we have two simple equations:
1) 100%=14.2
2) x%=80
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:
100%/x%=14.2/80
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 80 is what percent of 14.2

100%/x%=14.2/80
(100/x)*x=(14.2/80)*x       - we multiply both sides of the equation by x
100=0.1775*x       - we divide both sides of the equation by (0.1775) to get x
100/0.1775=x
563.38028169014=x
x=563.38028169014

now we have:
80 is 563.38028169014% of 14.2
