1. first change 6 3/7 from a mixed number to 45/7. (6 * 7 + 3 over 7)
2. now you have: 45/7 divided by 4/9.
3. now, since you are dividing fractions, switch the second fraction and multiply, giving you:
45/7 (times)9/4
multiply it out to get 405/28

You would have to flip the 4/9 to be 9/4
45/7*9/4 = 405/28

Convert the compound number into a fraction:
6 3/7 = 45/7
(Doesn't matter that it is an improper fraction.)
"Divided by 4/9" is the same as "multiply by 9/4" so you need to calculate
(45/7) * (9/4)

(6 + 3/7) / (4/9) =
(45/7) / (4/9) =
(45*9) / (7*4) =
405/28
Can't be reduced.
