Answer 2

To calculate the expression step by step:

1. Calculate the first part: (6 - 9, 3/5) • (-1, 2/3)

   First, simplify the values inside the parentheses:

   • (6 - 9, 3/5) = (6 - 1.8) = 4.2

   Now, multiply 4.2 by (-1, 2/3): 4.2 • (-1, 2/3) = -4.2 • (2/3) = -8/5

2. Calculate the second part: -12 ÷ (--3/4 + 1/8)

   First, simplify the values inside the parentheses:

   • (--3/4 + 1/8) = (3/4 + 1/8) = (6/8 + 1/8) = 7/8

   Now, divide -12 by 7/8: -12 ÷ (7/8) = (-12) * (8/7) = -96/7

3. Now, subtract the result from step 2 from the result in step 1:

   -8/5 - (-96/7) = -8/5 + 96/7

To add these fractions, you'll need to find a common denominator, which is 35 in this case:

• Multiply -8/5 by 7/7 to make the denominators the same:

  • ( -8/5 * 7/7 ) = (-56/35)

• Multiply 96/7 by 5/5 to make the denominators the same:

  • (96/7 * 5/5) = (480/35)

Now, you can add the fractions:

(-56/35) + (480/35) = 424/35

So, the final result of the expression is 424/35.
