To find out how many hours the figure skater will practice in 9 weeks, we can use the following calculations:
- The skater practices for 9 hours each day.
- There are 7 days in a week.
First, we calculate the number of hours practiced in one week: \[ 9 , \text{hours/day} \times 7 , \text{days/week} = 63 , \text{hours/week} \]
Next, we calculate the total practice time over 9 weeks: \[ 63 , \text{hours/week} \times 9 , \text{weeks} = 567 , \text{hours} \]
Therefore, the skater will practice a total of 567 hours in 9 weeks.
