Question

3 1/2 *5, 2 1/2 *5/6

Answer 1

$3\frac{1}{2}$ * 5 = $\frac{7}{2}$ * 5 = $\frac{35}{2}$ = $17\frac{1}{2}$ = 17.5

$2\frac{1}{2}$ * $\frac{5}{6}$ = $\frac{5}{2}$ * $\frac{5}{6}$ = $\frac{25}{12}$ = $2\frac{1}{12}$ = 2.083

Answer 2

To calculate the given expressions, let's simplify the mixed numbers first:

1. 3 1/2 * 5: 3 1/2 can be written as an improper fraction: (3 * 2 + 1)/2 = 7/2

   Now we can multiply: (7/2) * 5 Multiplying numerators: 7 * 5 = 35 Multiplying denominators: 2 * 1 = 2

   Therefore, 3 1/2 * 5 = 35/2, which can also be expressed as 17 1/2.

2. 2 1/2 * 5/6: 2 1/2 can be written as an improper fraction: (2 * 2 + 1)/2 = 5/2

   Now we can multiply: (5/2) * (5/6) Multiplying numerators: 5 * 5 = 25 Multiplying denominators: 2 * 6 = 12

   Therefore, 2 1/2 * 5/6 = 25/12.

To summarize:

• 3 1/2 * 5 = 17 1/2 or 35/2
• 2 1/2 * 5/6 = 25/12
