dots here That's five there and two on the third

00:24

thing We feel you brandon Last minute panic wrapping is

00:31

the worst Not that we're speaking from personal experience or

00:34

anything Each Mark indicates 1 ribbon in the given length

00:37

there So calculate the number of marx by the length

00:40

of the ribbon and add the results together to find

00:42

the length of ribbon Brandon already has a neck It's

00:45

just three of these things Time to fourth and five

00:47

times in this a third and then two times two

00:50

thirds there Adam altogether got three fourth five thirds plus

00:53

four thirds And what is that That's nine twelve mil

00:56

by both sides top and bottom by three there and

00:58

then on top and bottom by four For these guys

01:01

get nine Plus twenty is twenty nine and then sixteen

01:05

That's forty five twelve and divide what are dividing into

01:08

their by three I guess that's forty five so that

01:11

be fifteen force That's it So we're looking for the

01:13

difference between fifteen force beat and five feet which would

01:17

be much easier if we were dealing with fractions of

01:19

the same common denominator Per usual We gotta find one

01:22

So let's see Five feet is the same as twenty

01:26

over four feet and we're going to take twenty over

01:28

four and then subtract the fifteen force that gets us

01:31

five force So that's it Brandon needs just over one

01:34

foot of ribbon We're not entirely sure where he's going

01:37

to find it but we're sure he'll you know make 00:01:39.287 --> [endTime] it happens That's it The answer is
