To find the total time Aaron spent reading comics last week based on the provided information, we will add up the time he spent reading each day.
The times are represented as follows:
- \( \frac{1}{4} \) hour (1 day)
- \( \frac{3}{4} \) hour (3 days)
- \( 1 \) hour (1 day)
Now, let's calculate the total time spent reading:
-
The time spent on the days where he read \( \frac{1}{4} \) hour: \[ 1 \times \frac{1}{4} = \frac{1}{4} \text{ hours} \]
-
The time spent on the days where he read \( \frac{3}{4} \) hour: \[ 3 \times \frac{3}{4} = \frac{9}{4} \text{ hours} \]
-
The time spent on the day where he read \( 1 \) hour: \[ 1 \times 1 = 1 \text{ hour} = \frac{4}{4} \text{ hours} \]
Now, we add these amounts together: \[ \frac{1}{4} + \frac{9}{4} + \frac{4}{4} \]
To do this, we can combine the fractions since they all have the same denominator (4): \[ \frac{1 + 9 + 4}{4} = \frac{14}{4} \]
Now, simplify \( \frac{14}{4} \): \[ \frac{14 \div 2}{4 \div 2} = \frac{7}{2} \]
Finally, we can convert \( \frac{7}{2} \) into a mixed number: \[ \frac{7}{2} = 3 \frac{1}{2} \]
So, the total time Aaron spent reading comics last week is: \[ \boxed{3 \frac{1}{2}} \text{ hours} \]
