Answer 2

To solve this expression, we'll follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction) and simplify step by step:

1. First, let's add the fractions in the parentheses:

   (1 7/9 + 5 1/3) = (16/9 + 16/3)

   To add these fractions, you need a common denominator, which is 9:

   (16/9 + 16/3) = (16/9 + 48/9) = 64/9

2. Next, multiply the result by 3:

   64/9 * 3 = (64 * 3) / 9 = 192/9

3. Reduce the fraction, if possible. In this case, you can divide both the numerator and denominator by their greatest common factor, which is 3:

   (192/9) ÷ 3 = (64/3)

4. Now, let's move on to the second part of the expression:

   (12 - 7 3/5)

   First, convert the mixed number to an improper fraction:

   7 3/5 = 38/5

   Now, subtract:

   (12 - 38/5)

5. To subtract these numbers, you need a common denominator, which is 5:

   (60/5 - 38/5) = (60 - 38) / 5 = 22/5

6. Finally, divide the result by 4:

   (22/5) ÷ 4 = (22/5) * (1/4) = (22/20)

7. Reduce the fraction, if possible. In this case, you can divide both the numerator and denominator by their greatest common factor, which is 2:

   (22/20) ÷ 2 = (11/10)

So, the final result is (11/10).
