Converting Time to Decimal Fractions

To express the given times in hours using decimal fractions, we can convert each time to hours and then represent the result as a decimal fraction.

1. 8 minutes 36 minutes: - 8 minutes = 8/60 hours = 0.1333 hours - 36 minutes = 36/60 hours = 0.6 hours - Therefore, 8 minutes 36 minutes = 0.1333 + 0.6 = 0.7333 hours.

2. 2 hours 12 minutes: - 2 hours = 2 hours - 12 minutes = 12/60 hours = 0.2 hours - Therefore, 2 hours 12 minutes = 2 + 0.2 = 2.2 hours.

3. 2 hours 15 minutes: - 2 hours = 2 hours - 15 minutes = 15/60 hours = 0.25 hours - Therefore, 2 hours 15 minutes = 2 + 0.25 = 2.25 hours.

4. 3 hours 48 minutes: - 3 hours = 3 hours - 48 minutes = 48/60 hours = 0.8 hours - Therefore, 3 hours 48 minutes = 3 + 0.8 = 3.8 hours.

Therefore, the times expressed in hours using decimal fractions are: - 8 minutes 36 minutes = 0.7333 hours - 2 hours 12 minutes = 2.2 hours - 2 hours 15 minutes = 2.25 hours - 3 hours 48 minutes = 3.8 hours
