80.72 is what percent of 377.21 - 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 377.21 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 377.21, so we can write it down as 100%=377.21.
4. We know, that x% equals 80.72 of the output value, so we can write it down as x%=80.72.
5. Now we have two simple equations:
1) 100%=377.21
2) x%=80.72
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%=377.21/80.72
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 80.72 is what percent of 377.21

100%/x%=377.21/80.72
(100/x)*x=(377.21/80.72)*x       - we multiply both sides of the equation by x
100=4.6730673934589*x       - we divide both sides of the equation by (4.6730673934589) to get x
100/4.6730673934589=x
21.399220593303=x
x=21.399220593303

now we have:
80.72 is 21.399220593303% of 377.21
