What part of an hour elapses from 3:12 P.M. to 4:30 P.M.?
sergejj [24]

Answer: \frac{13}{10} of an hour.


Step-by-step explanation:

1. You know that it is from 3:12 p.m. (48 minutes before 4:00 p.m.) to 4:30 p.m. (30 minutes after 4:00 p.m.)

2. Therefore, you must make the following addition:

48minutes+30minutes=78minutes

This is 78 minutes out of 1 hour (60 minutes).

3. Therefore, you have the following fraction:

\frac{78}{60}

4. Now, you must reduce the fraction:

\frac{78}{60}=\frac{13}{10}

5. The answer is 13/10 on an hour.
