After school,Philipe spent 1 3/4 hours of baseball practice, 2 1/4 hours on homework, and 1/4 hour getting ready for bed.Wich is the most reasonable estimate for how long he spent on his activities:3 hours,4 hours,or 5 hours?Explain
4 hours. 1 3/4 is about 2, and 2 1/4 rounds to 2. 1/4 would round to 0, but it would not affect the estimate's accuracy much because we rounded up by 1/4 on 1 3/4 already. Philipe spent about 4 hours on activities.
