Answer:

51/2, also known as 25 1/2

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*(1*2+1)/(2)

2. Simplify 1 × 2 = 2.


17*(2+1)/(2)

3. Simplify 2 + 1 = 3


17*(3)/(2)

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


(17*3)/(2)

5. Simplify 17 × 3 = 51.


(51)/(2)

Mixed Number =
25(1)/(2)
