Describe or show how to find the following product using both an algorithm and a diagram:

3 x 3/4

1/4 x 2/3

and

1 1/3 x 2

First expression:

Step 1: Multiply numerators and denominators.

Second expression:

Step 1: Multiply numerators and denominators.

Third expression:

Step 1: Convert mixed fraction into improper fraction:

Step 2: Replace the improper form into the expression

Step 2: Multiply numerators and denominators.

The diagram is shown below. Basically the steps we follow are the same as if it were using algorithms.
