Eighty percent of the dogs have completed obedience classes. how many of the dogs have completed obedience classes? five dogs of different breeds 4 dogs 3 dogs 2 dogs 1 dog

Let
x> number of dogs that completed the obedience class

we know that
total number of dogs=5
Eighty percent of the dogs have completed obedience classes
so
x=0.80*5> x=4

the answer is
4 dogs have completed obedience classes

4 dogs have completed the obedience classes

Explanation:
We are given that 80% of the dogs completed the obedience classes and that the total number of dogs who attended the class was 5

This means that 80% of the 5 dogs have completed the class

Therefore:
number of dogs that completed the class = 80% * 5
= 0.8 * 5
= 4 dogs
