To find the product  3/7 x 4/9, cameron found the gcf of 3 and 9. he then multiplied the fractions 1/7 and 4/9 to find the product 4/63. what was cameron's error?

He should have found the GFC of 7 and 9.

Step-by-step explanation:

To something like this you need to find the GFC of the bottom numbers of both of the fractions.

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
