Question

An algebra class normally has y students, but today it is just 2/3 full. Express the number of students in class today terms of y.

Answer 1

2/3y

Explanation:

If the class usually has y students and has 2/3 today, it can be represented by 2/3y.

Since multiplying a number or variable by 2/3 makes it 2/3 of the amount, 2/3y will represent the people in the class.

So, in terms of y, 2/3y represents the number of students in class today.
