To find the time Naysha spends listening to the radio over a 7-day period, we can multiply the daily time (5/6 hour) by the number of days (7 days).
Here are the expressions provided and their meanings:
- 12/6 (This evaluates to 2, which does not represent the time spent over 7 days.)
- 7×5/6 (This represents the total time: 7 times 5/6 = 35/6.)
- 7+5/6 (This does not represent the total time but rather adds an extra 5/6 to 7.)
- 35/6 (This is the total time spent listening to the radio over 7 days.)
- 5/6+5/6+5/6+5/6+5/6+5/6+5/6 (This also is a correct representation as it adds up the time for each day over 7 days.)
The expressions that correctly represent the time Naysha spends listening to the radio in a 7-day period are:
- 7×5/6
- 35/6
- 5/6+5/6+5/6+5/6+5/6+5/6+5/6
So, the correct three expressions are: 7×5/6, 35/6, and 5/6+5/6+5/6+5/6+5/6+5/6+5/6.
