Estimating Products
The problem is asking for the estimated number of glasses of water that Larry would drink in a specified time. The phrase "about how many" indicates that you should not look for the exact value but the estimated number.
To find the answers, you have to estimate the factors first by applying the rules in rounding off numbers, then multiply.
1. a week
6.48 = 6
days in a week = 7
6 × 7 = 42
Answer: about 42 glasses of water in a week
2. a month
6.48 = 6
days in a month = 30
6 × 30 = 180
Answer: about 180 glasses of water in a month
3. a year
6.48 = 6
days in a year = 365.25 = 365
6 × 370 = 2220
Answer: about 2,190 glasses of water in a year
4. a decade
6.48 = 6
days in a decade = 3652.5 = 3653
6 × 3653 = 21918
Answer: about 21,918 glasses of water in a decade
5. 5 days
6.48 = 6
6 × 5 = 30
Answer: about 30 glasses of water in 5 days
