Respuesta :

C. 3, C. 33 - For the first, when you divide fractions, you would flip the second fraction to get a multiplication problem. So 2/7 divided by 3 is equal to 2/7 x 1/3, making 2/21. 
For the second, 2 and 1/4 is equal to 9/4 then you multiply by 12/1, getting 108/4, or 27. Then you just add. 
YOUR WELCOME.
