basically the answer is 2n-1 2n comes from the difference to get from 1 to three and the -1 from 2n to get to 1 you need to minus 1 so you get -1
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!
