21. ) a. 16/24 - 1/12 = 16/24 - 2/24 = 14/24 reduces to 7/12
b. 1/12 (.083) eating, 1/8 (0.125) on the phone.....on the phone for more
time.....1/8 - 1/12 = 12/96 - 8/96 = 4/96 reduces to 1/24 more time
c. if she was awake 16/24, then she was asleep 8/24 which reduces to
1/3
d. 1/8 talking on the phone, 4/24 visiting ...she spent more time visiting. 4/24 - 1/8 = 4/24 - 3/24 = 1/24 more time.
22.) 11/12 - (1/12 + 1/12 + 1/2) = 11/12 - (1/6 + 1/2) = 11/12 - (1/6 + 3/6) =
11/12 - 4/6 = 11/12 - 8/12 = 3/12 reduces to 1/4 hr. time remaining
23.) I believe u put ur own numbers in this one...
u have a 24 hr day.....lets say u sleep 8/24....u eat 3/24 of the day and u watch t.v. 5/24 of the day .....totaling 16/24....which leaves 8/24 of the day left to do other things. You can put ur own numbers in if u wish.
