Answer 2

Sure, I'd be happy to help you with the expression. Let's break it down step by step:

Step 1: Simplify the expressions inside parentheses first.

1 1/2 - 3/5 = 1 + 1/2 - 3/5 = 3/2 - 3/5 = (53 - 23) / (2*5) = (15 - 6) / 10 = 9/10

(-3/4) - (5/6) = (-18/24) - (20/24) = -38/24

Step 2: Perform the multiplication:

-4 1/6 * (9/10) + (-38/24) * 6

Step 3: Convert -4 1/6 to an improper fraction:

-4 1/6 = -(24/6) + (1/6) = -25/6

Step 4: Multiply -4 1/6 by 9/10:

(-25/6) * (9/10) = (-259) / (610) = -225/60

Step 5: Simplify -225/60:

-225/60 = -(225/3) / (60/3) = -75/20

Step 6: Multiply -38/24 by 6:

(-38/24) * 6 = (-38*6) / 24 = -228/24

Step 7: Simplify -228/24:

-228/24 = -(228/12) / (24/12) = -19/2

Now, we have:

-75/20 + (-19/2)

Step 8: Find the common denominator for both fractions, which is 20:

-75/20 = -75/20 -19/2 = -19 * 10/2 * 10 = -190/20

Step 9: Add the fractions:

-75/20 + (-190/20) = (-75 - 190) / 20 = -265/20

Step 10: Simplify the result:

-265/20 = -(265/5) / (20/5) = -53/4

The final result is -53/4.
