Cathy wakes up at 7:00 am each morning. She spends 1/10 hour making her bed, 1/5 hour eating breakfast, and 1/2 hour getting ready for school. How long does Cathy spend doing these things each morning?
0.1 + 0.2 + 0.5 = _____ of an hour
0.8
To find out how long Cathy spends doing these things each morning, we can add up the time she spends on making her bed, eating breakfast, and getting ready for school.
First, let's convert the time fractions to a common denominator.
- 1/10 hour becomes 3/30 hour
- 1/5 hour becomes 6/30 hour
- 1/2 hour becomes 15/30 hour
Now we can add the fractions together:
3/30 + 6/30 + 15/30 = 24/30 hour
To simplify the fraction, we can divide both numerator and denominator by the greatest common divisor, which is 6:
24/6 = 4/5 hour
Therefore, Cathy spends 4/5 hour (or 48 minutes) doing these things each morning.
