80 is what percent of 1178 - 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 1178 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 1178, so we can write it down as 100%=1178.
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%=1178
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%=1178/80
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 1178

100%/x%=1178/80
(100/x)*x=(1178/80)*x       - we multiply both sides of the equation by x
100=14.725*x       - we divide both sides of the equation by (14.725) to get x
100/14.725=x
6.7911714770798=x
x=6.7911714770798

now we have:
80 is 6.7911714770798% of 1178
