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.
[tex]17*\frac{1*2+1}{2}[/tex]
2. Simplify 1 × 2 = 2.
[tex]17*\frac{2+1}{2}[/tex]
3. Simplify 2 + 1 = 3
[tex]17*\frac{3}{2}[/tex]
4. Add it in one equation. (Since 17 = 17/1, it equals to 17*3/2, shown below)
[tex]\frac{17*3}{2}[/tex]
5. Simplify 17 × 3 = 51.
[tex]\frac{51}{2}[/tex]
Mixed Number = [tex]25\frac{1}{2}[/tex]
