Let's analyse this. We have 4/5 and 2 with 3/4. First of all we must change the mixed fraction into a top heavy fraction to get 4/5 and 11/4 (2x4 is 8 +3 is 11.)
Now we have two fractions 4/5 and 11/4.
Now finally we need to MASH the fractions together to get 4x11/5x4.
This is because in fractions where a/b x c/d is the question we can find an answer by getting ac/bd.
Thus our answer is 44/20.
Simplifying down we get 22/10 and 11/5.
