Question

V = 2 1/2× 2 × 1 1/2

Answer 1

Answer:

$v = \frac{15}{2}$

Step-by-step explanation:

$1. \: v = \frac{2 \times 2 + 1}{2} \times 2 \times 1 \frac{1}{2} \\ 2. \: v = \frac{4 + 1}{2} \times 2 \times 1 \frac{1}{2} \\ 3. \: v = \frac{5}{2} \times 2 \times 1 \frac{1}{2} \\ 4. \: v = \frac{5}{2} \times 2 \times \frac{1 \times 2 + 1}{2} \\ 5. \: v = \frac{5}{2} \times 2 \times \frac{2 + 1}{2} \\ 6. \: v = \frac{5}{2} \times 2 \times \frac{3}{2} \\ 7. \: v = 5 \times \frac{3}{2} \\ 8. \: v = \frac{5 \times 3}{2} \\ 9. \: v = \frac{15}{2}$
