To find out how many hours Rebecca spent on her phone from Monday through Thursday, we will first convert all the fractions and add them up.
The table shows the following usage:
- Monday: 1,1/4 hours = 1 + 1/4 = 5/4 hours
- Tuesday: 2/4 hours = 1/2 hours
- Wednesday: 1,2/4 hours = 1 + 2/4 = 1 + 1/2 = 3/2 hours
- Thursday: 1,1/4 hours = 1 + 1/4 = 5/4 hours
Now we will add these amounts together:
-
First, convert everything to a common denominator where possible. The common denominator for 4 and 2 is 4.
- Monday: 5/4
- Tuesday: 2/4 (1/2 converted to 2/4)
- Wednesday: 6/4 (3/2 converted to 6/4)
- Thursday: 5/4
-
Now we can add them:
\( \frac{5}{4} + \frac{2}{4} + \frac{6}{4} + \frac{5}{4} = \frac{5 + 2 + 6 + 5}{4} = \frac{18}{4} \)
-
Now simplify \( \frac{18}{4} \) to get \( 4 , \frac{2}{4} = 4 , \frac{1}{2} \).
The total number of hours Rebecca spent on her phone from Monday through Thursday is 4,2/4 hours or 4.5 hours.
Based on the answer choices provided, the answer is:
4,2/4 hours.
