Answer 3

To solve the expression 1 4/9 * 1 5/13 - 2 1/12 * 4/15, let's break it down step by step:

First, let's simplify the multiplication and division separately:

1 4/9 * 1 5/13 = (9 + 4)/9 * (13 + 5)/13 = 13/9 * 18/13 = (13 * 18)/(9 * 13) = 234/117 = 2

2 1/12 * 4/15 = (12 + 1)/12 * 4/15 = 13/12 * 4/15 = (13 * 4)/(12 * 15) = 52/180 = 13/45

Now, let's subtract the two results:

2 - 13/45 = (2 * 45 - 13)/45 = (90 - 13)/45 = 77/45

Therefore, the expression 1 4/9 * 1 5/13 - 2 1/12 * 4/15 is equal to 77/45.
