To find the product of 3/7 × 4/9, Cameron simplified 3/7 to 1/7 and then multiplied the fractions 1/7 and 4/9 to find the product 4/63. What is Cameron's error?


Cameron divided a factor in one of the numerators by the GCF but did not divide a factor in one of the denominators by the GCF. He should have simplified 4/9 (Fill in the answer) to and multiplied 1/7 and (Fill in the answer) to find the product (Fill in the answer).

If anyone can solve this problem it is the last one I am stuck on in my assignment I only have one hour left. Thank you.

3/7 × 4/9

= 3/7 × 4/(3×3)
= 1/7 × 4/(1×3)
= 4/21
