Is this the only part of the question? cause if so its he read for 45 minutes :D
3/4 of an hour equals 45 minutes because 4/4 (one), is equal to 60 minutes or an hour. 2/4 of an hour is 30 minutes. 1/4 of an hour is 15 minutes. 1/4 multiplied by 3 is 45 minutes and that equals 3/4. I hope this helps!
