Transcript

00:01

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
