Furstly, multiplying mixed fractions together is chaotic. Convert them into improper fractions first.

(22/3) * (20/3) * (27/10)

Secondly, don't start multiplying all out! Look for common factors. There are two 3's at the denominator, and 27 is 3^3 at the numerator. Cross them out!

22 * 20 * 3 / 10

Hey! There are multiples of 10 too!

22 * 2 * 3

= (11 * 2) * 2 * 3

= 11 * 12

= 132

That leads to option 3!
