Answer:

She is on the bus [tex]6\frac{1}{4}[/tex] hours each week

Step-by-step explanation:

From the information given we know that:

  • [tex]1 \frac{1}{4} \frac{hours}{weekday}[/tex]
  • There are 5 weekdays (Monday through Friday)

So, to find the hours she spends on the bus you need to:

  1. Convert mixed numbers to improper fraction with this:

[tex]a\frac{b}{c}=\frac{a\cdot \:c+b}{c}[/tex]

[tex]1\frac{1}{4}=\frac{1\cdot 4+1}{4}=\frac{5}{4}[/tex]

    2. Multiply fractions

[tex]\frac{5}{4}\cdot \frac{5}{1} = \frac{25}{4}[/tex]

   3. Convert improper fractions to mixed numbers

[tex]\mathrm{Convert\:to\:mixed\:number:\:Quotient\frac{Remainder}{Divisor}}[/tex]

[tex]\frac{25}{4}=6\frac{1}{4}[/tex]
