Answer 2

Let's break it down step by step:

1. Subtract Fractions:

   • $\frac{6}{1} - \frac{3}{1} = \frac{3}{1}$

2. Convert Mixed Numbers to Improper Fractions:

   • $\frac{3}{1} = \frac{3 \times 1}{1 \times 1} = \frac{3}{1}$

3. Subtract Fractions:

   • $\frac{3}{1} - \frac{17}{36}$

4. Find a Common Denominator (in this case, 36):

   • $\frac{3 \times 36}{1 \times 36} - \frac{17}{36} = \frac{108}{36} - \frac{17}{36}$

5. Subtract Numerators:

   • $\frac{108 - 17}{36} = \frac{91}{36}$

6. Multiply by $\frac{1}{2}$:

   • $\frac{91}{36} \times \frac{1}{2} = \frac{91 \times 1}{36 \times 2} = \frac{91}{72}$

7. Subtract Whole Number:

   • $\frac{91}{72} - \frac{4 \times 72}{1 \times 72} = \frac{91}{72} - \frac{288}{72}$

8. Subtract Numerators:

   • $\frac{91 - 288}{72} = \frac{-197}{72}$

9. Divide by $\frac{12}{20}$:

   • $\frac{-197}{72} \div \frac{12}{20} = \frac{-197}{72} \times \frac{20}{12}$

10. Simplify the Fraction:

    • $\frac{-197 \times 5}{72 \times 3} = \frac{-985}{216}$

So, $(6 \frac{7}{12} - 3 \frac{17}{36}) \times \frac{1}{2} - 4 \frac{1}{3} \div \frac{12}{20} = -\frac{985}{216}$.
