26.9 is what percent of 80 - 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 80 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 80, so we can write it down as 100%=80.
4. We know, that x% equals 26.9 of the output value, so we can write it down as x%=26.9.
5. Now we have two simple equations:
1) 100%=80
2) x%=26.9
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%=80/26.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 26.9 is what percent of 80

100%/x%=80/26.9
(100/x)*x=(80/26.9)*x       - we multiply both sides of the equation by x
100=2.9739776951673*x       - we divide both sides of the equation by (2.9739776951673) to get x
100/2.9739776951673=x
33.625=x
x=33.625

now we have:
26.9 is 33.625% of 80
