Answer 2

Answer:

51/2, also known as 25 1/2

Step-by-step explanation:

Each = Multiply.

If there's 17 students, they all give 1 1/2 minute speech, then you multiply to get the minutes of how long it will take.

1. Convert 1 1/2 to improper.

$17*\frac{1*2+1}{2}$

2. Simplify 1 × 2 = 2.

$17*\frac{2+1}{2}$

3. Simplify 2 + 1 = 3

$17*\frac{3}{2}$

4. Add it in one equation. (Since 17 = 17/1, it equals to 17*3/2, shown below)

$\frac{17*3}{2}$

5. Simplify 17 × 3 = 51.

$\frac{51}{2}$

Mixed Number = $25\frac{1}{2}$
