Description: Learn to compare expressions with positive and negative fractions. Created by Sal Khan. We have four different expressions here, and what I want you to do is think about which of these expressions are equal to negative 2/3. Well, both six and nine are divisible by 3, so let's divide them both by 3 to try to get this fraction in a simpler form. This expression does not equal negative 2/3, so I'll write "no" for that one.
