Answer:
I am pretty sure the answer is 19/30
Step-by-step explanation:
If u turn 2 1/9 ÷ 3 1/3 into improper fractions u will get 19/9 Divided by 10/3
Then u do the butterfly. So this would be 9 x 10 =90 and 19 x 3 =57 so this is what it looks like 57/90 and that can be simpflyed into 19/30. Becasue 3 x 19 = 57 and 3 x 30 = 90
