At the beginning of the day, Margaret had 72 ice cream cones. By noon, she had $\frac{2}{3}$ as many cones as she had at the beginning of the day. By the end of the day, she only had $\frac{2}{3}$ as many cones as she had at noon. How many ice cream cones does she have at the end of the day?
I need to find out how many cones Margaret had at noon and then at the end of the day. To find out how many cones she had at noon, I can multiply the number of cones she had at the beginning of the day by $\frac{2}{3}$. So, at noon, she had 72 times $\frac{2}{3}$ cones, which is 48 cones. To find out how many cones she had at the end of the day, I can multiply the number of cones she had at noon by $\frac{2}{3}$ again. So, at the end of the day, she had 48 times $\frac{2}{3}$ cones, which is 32 cones.
