Answer:4/9Step-by-step explanation:(4/9)/(7/9) is equal to (4/9)*(9/7) because "keep change flip." So we keep the first number, change division into multiplication, and flip 4/9 (basically find the reciprocal) and that is 9/4. Thus, (4/9)*(9/7) is equal to 4/9 because the 7's cancel. I hope this helped!
