1. First, note that "product" refers to "multiplication"

2. Set up the equation

(7/8)(4/21) = ?

3. Multiply the numerators and then multiply the denominators together

(7)(4)/(8)(21) = 28/168

4. Reduce the fraction buy factoring out (and thus cancelling) the greatest common factor (GCF)

(28)/(168) = (28)(1)/(28)(6)

5. The GCF, 28, cancels (as 28/28 is 1) and the resulting fraction is your answer

**1/6**

Hi Chris;

SINCE I LAST POSTED THIS, I REALIZED I MADE A MISTAKE. PLEASE SEE BELOW FOR THE CORRECT SOLUTION. I APOLOGIZE!!!!!!!!!!!!!!!!!

7/8 x 4/21

(7x4)/(8x21)=28/168

Let's divide the top and bottom by 7...

(28/7)/(168/7)=4/24

Let's divide the top and bottom by 4...
