The easy way to do this to get both in the form of A/B3 2/3 = 9/3 + 2/3 = 11/3
14 2/5 = 70/5 + 2/5 = 72/5
11/3 x 72/5 is:
(11x72)/(3x5) = 792/15
Divide by 3 above and below to give:
264/5
which is
52 4/5
Hope this helps!

(3 2/3)(14 2/5)
= [(3 x 3 + 2)/3][(5 x 14 + 2)/5]
= [11/3][72/5]
= (11 x 72)/(3 x 5)
= 792/15
= 264/5
= 52 4/5
= [(3 x 3 + 2)/3][(5 x 14 + 2)/5]
= [11/3][72/5]
= (11 x 72)/(3 x 5)
= 792/15
= 264/5
= 52 4/5
