Answer:
Answers A and B
Step-by-step explanation:
To divide fractions, you keep, change, flip. Keep the first fraction the same, 4/11. Change the division sign into a multiplication sign. Finally, find the reciprocal or "flip" the last fraction into 15/9. This makes the equation 4/11 x 15/9. Multiply across the top to get 60, and the bottom to get 99. This makes 60/99. Therefore, answer A is correct. Find some more equivelent fractions by multiplying or dividing the top and bottom by the same amount. In this proccess, you can find that answer B is also correct.
