80 is what percent of 930 - 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 930 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 930, so we can write it down as 100%=930.
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%=930
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%=930/80
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 930

100%/x%=930/80
(100/x)*x=(930/80)*x       - we multiply both sides of the equation by x
100=11.625*x       - we divide both sides of the equation by (11.625) to get x
100/11.625=x
8.6021505376344=x
x=8.6021505376344

now we have:
80 is 8.6021505376344% of 930
