All right you math people have got some weird word
- 00:04
problems for you Here we go Billy decides to record
- 00:08
the amount of time he reads outside of class for
- 00:10
each book that he reads While the logs from the
- 00:13
time he spent reading slapped her house five otherwise pronounced

- 00:16
slaughterhouse five is shown below it's we got a quarter
- 00:19
and a half and then three fourth with little red
- 00:22
dot thing He's here So how long has billy spent
- 00:24
reading Slaughterhouse five to date Well this billy's reality seems
- 00:32
to be way better than that of the main character
- 00:34
of slaughterhouse five While this billy sitting around reading and
- 00:38
making marks in his log book on the other billy
- 00:40
is getting firebombed and kidnapped by aliens for their earthlings
- 00:44
Ooh alright we'll each mark above forthe means that billy
- 00:47
red for one fourth of an hour which he did
- 00:50
on four separate occasions He one two three four with
- 00:53
that in mind set up an expression that calculates the
- 00:55
total amount of time he read taking the other two
- 00:58
columns into consideration And that gets us this little equation
- 01:01
thinking four times a fourth and eight times a half
- 01:03
and then three times three fourths Well that's less than
- 01:06
ideal for adding fractions this little thing here So let's
- 01:09
convert all this stuff and improper fractions with common denominators
- 01:12
of four Well once that's done we can then convert
- 01:15
the final answer back into a mixed number So that
- 01:18
gets us What is that for Over four times one
- 01:21
Four So that's four force that we have eight times
- 01:24
a half That's eight over to which gets us We'll
- 01:27
do that in a force of sixteen over for some
- 01:29
We have three times three fourths seventy three times three
- 01:32
is nine And i'm not for thinkit's four plus sixteen
- 01:34
plus nine twenty nine over four And then if we
- 01:37
make that a mixed number we have seven and a
- 01:39
quarter So the answer is seven hours and then some
- 01:42
Since one fourth is able to point two five Well
- 01:44
it might be tempting to define and then some as
- 01:46
twenty five minutes is indeed But guess again One fourth
- 01:50
of sixty minutes i'ii one hour is fifteen minutes So
- 01:53
billy spent seven hours and fifteen minutes on his book
- 01:56
so far But we can't help wonder why bill his
- 01:59
keeping this log book Maybe he thinks it's fun to
- 02:02
see time all at once Careful there billy You might
- 02:05
find yourself being hauled off to the trial family Dorian
- 02:08
zoo pretty soon
