Final answer:
To calculate the number of 3-month periods in 17 years, multiply 17 years by 12 to get the total months and then divide by 3. There are 68 three-month periods in 17 years.
Step-by-step explanation:
To find out how many 3-month periods are in 17 years, we need to determine the total number of months in 17 years and then divide that number by 3, since each period is 3 months long.
First, we calculate the total number of months in 17 years:
- 1 year = 12 months
- 17 years = 17 × 12 months
- 17 years = 204 months
Next, we divide the total number of months by 3 to find the number of 3-month periods:
- 204 months ÷ 3 months/period = 68 periods
Therefore, there are 68 three-month periods in 17 years.
