Answer 2

To calculate the expression:

3 3/4 * (-2/15) - 1 1/5 * (-5/12)

First, convert the mixed numbers into improper fractions:

3 3/4 = (4 * 3 + 3) / 4 = 15/4 1 1/5 = (5 * 1 + 1) / 5 = 6/5

Now, we can rewrite the expression:

(15/4) * (-2/15) - (6/5) * (-5/12)

Now, multiply the fractions:

(15/4) * (-2/15) = -1/4 (6/5) * (-5/12) = -1/2

Now, subtract the results:

-1/4 - (-1/2)

To subtract two fractions, you need to find a common denominator. In this case, the common denominator is 4. So, we'll rewrite the fractions with a common denominator:

-1/4 - (-1/2) = -1/4 + 2/4

Now that they have the same denominator, you can add them:

-1/4 + 2/4 = 1/4

So, the result of the expression is 1/4.
