For a multiplication problem such as this, it helps to rearrange or factor the numerators and denominators.
(22/9)*(9/11)*(3/8)
= (22/11)*(9/9)*(3/8) (here, we have rearranged the 9s so we can see they cancel)
= (2*11/11)*(3/8) (here, we have factored 22, so we can see that the 11s cancel)
= (3*2)/(4*2) (here, we have factored 8 so we can see that the 2s cancel)
= 3/4
(22/9)*(9/11)*(3/8)
= (22/11)*(9/9)*(3/8) (here, we have rearranged the 9s so we can see they cancel)
= (2*11/11)*(3/8) (here, we have factored 22, so we can see that the 11s cancel)
= (3*2)/(4*2) (here, we have factored 8 so we can see that the 2s cancel)
= 3/4
