Answer 2

Let's break down the expression step by step:

1. Calculate the fractions:

   • $2½$ is the same as $2 + \frac{1}{2}$, which equals $2.5$.
   • $1¾$ is the same as $1 + \frac{3}{4}$, which equals $1.75$.

2. Calculate the fractions inside the parentheses:

   • $2½ + 1¾$ = $2.5 + 1.75$ = $4.25$.

3. Calculate the products and divisions within the expression:

   • $4 \times (2½ + 1¾)$ = $4 \times 4.25$ = $17$.
   • $6⅔$ is the same as $6 + \frac{2}{3}$, which equals $6.666...$.
   • $4⅘$ is the same as $4 + \frac{4}{5}$, which equals $4.8$.
   • $6⅔ + 4⅘$ = $6.666... + 4.8$ = $11.466...$.
   • $(6⅔ + 4⅘) ÷ 2$ = $11.466... ÷ 2$ = $5.733...$.

4. Substitute the results back into the original expression:

   • $17 - (5.733...)$ ≈ $11.266...$.

So, the approximate value of the expression $4 \times (2½ + 1¾) - (6⅔ + 4⅘) ÷ 2$ is approximately $11.266$.
