in each of two different fourth-grade classes, 1/3 of the members are girls. does each class have the same numbers of girls.
It's the same answer I posted this morning for you.
Didn't you read it?

To determine if each class has the same number of girls, we need to examine the fractions and calculate the actual number of girls in each class.
Let's say the first fourth-grade class has N members. Since 1/3 of the members are girls, we can calculate the number of girls in that class as (1/3) * N.
Similarly, let's say the second fourth-grade class has M members. Again, since 1/3 of the members are girls, the number of girls in this class will be (1/3) * M.
Now, if we compare the number of girls in each class, we find that the first class has (1/3) * N girls, while the second class has (1/3) * M girls.
Since N and M are not defined or given, we cannot determine whether the two classes have the same number of girls without more information. Without specific values for N and M, we cannot make a conclusive statement about the equality of the number of girls in the two classes.
