80 is what percent of 72.6 - 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 72.6 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 72.6, so we can write it down as 100%=72.6.
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%=72.6
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%=72.6/80
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 72.6

100%/x%=72.6/80
(100/x)*x=(72.6/80)*x       - we multiply both sides of the equation by x
100=0.9075*x       - we divide both sides of the equation by (0.9075) to get x
100/0.9075=x
110.19283746556=x
x=110.19283746556

now we have:
80 is 110.19283746556% of 72.6
