2-91.

In parts (a) and (b) of problem 2‑89, the rectangular models for $\frac { 1 } { 2 }$ of $\frac { 1 } { 4 }$ and $\frac { 1 } { 4 }$ of $\frac { 1 } { 2 }$ looked different, but the answers were the same. Read the steps for the example given in the Math Notes box in this lesson for how to calculate $\frac { 2 } { 3 }$ of $\frac { 2 } { 5 }$. Then follow the steps and draw a similar rectangle to show $\frac { 2 } { 5 }$ of $\frac { 2 } { 3 }$. Are the answers the same? Why or why not?

For help drawing a diagram, see the online homework help for problem 2-90.

Mathematically, what do we mean when we say $\frac{2}{5}\text{ of }\frac{2}{3}?$

What operation is being used? Does the order matter for this operation?
