Answer 2

To solve this expression, you can follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division, and Addition and Subtraction. Let's solve the expression step by step:

1. Start by simplifying the expression inside the innermost parentheses: $12 \frac{7}{9} \times \frac{2}{7} = \frac{12 \times 7}{9} \times \frac{2}{7} = \frac{84}{9} \times \frac{2}{7} = \frac{168}{63}$.

2. Simplify the fraction: $\frac{168}{63} = \frac{8}{3}$.

3. Now, multiply the result from step 2 by 3 1/2: $3 \frac{1}{2} \times \frac{8}{3} = \frac{7}{2} \times \frac{8}{3} = \frac{56}{6}$.

4. Simplify the fraction: $\frac{56}{6} = \frac{28}{3}$.

So, the final result of the expression $3 \frac{1}{2} \times (12 \frac{7}{9} \times \frac{2}{7})$ is $\frac{28}{3}$, which is approximately 9.33 when rounded to two decimal places.
