Answer:
6.38 hours
Step-by-step explanation:
Identify the hundreds digit: the 7 in 3798
Identify the next smallest place value: the 9 in 3798
Is that digit greater than or equal to five? Yes, so round up.
Increase the hundreds digit by one, so 7 becomes 8. Every digit after becomes a zero.
3798 rounded to the nearest hundred is 6.3800
