77.91 is what percent of 443 - 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 443 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 443, so we can write it down as 100%=443.
4. We know, that x% equals 77.91 of the output value, so we can write it down as x%=77.91.
5. Now we have two simple equations:
1) 100%=443
2) x%=77.91
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%=443/77.91
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 77.91 is what percent of 443

100%/x%=443/77.91
(100/x)*x=(443/77.91)*x       - we multiply both sides of the equation by x
100=5.6860480041073*x       - we divide both sides of the equation by (5.6860480041073) to get x
100/5.6860480041073=x
17.58690744921=x
x=17.58690744921

now we have:
77.91 is 17.58690744921% of 443
