using units to solve problems- a la shmoop.

00:07

alright if you walk into someplace in Paris and ask for three yards of

00:10

fabric well they'll probably look at you like you're nuts. [man asks McDonalds worker for fabric]

00:13

first of all because they don't sell fabric at McDonald's. but also because

00:16

they used a different funky unit of measurement over there. that's silly

00:20

metric system. well you'll run into problems all the

00:23

time where you have to convert from one unit to another when dealing with

00:26

distances or lengths or weights. you name it. by metric system think like kilograms

00:33

instead of pounds and meters instead of yards. well the good news is that you

00:40

don't have to have all those conversions memorized. your brain has enough stuff to

00:45

worry about. all you really have to do is refer to a conversion chart. where

00:49

someone's already done the dirty work for you, [kid with messy face holds conversion chart]

00:51

and shmoop has one and it looks a little something like this- though all right say

00:56

you want to know how many miles some guy walked and another guy shoes. but you're

01:01

told that he only traveled 9.65 six kilometers well we can look up miles to

01:07

kilometers on our handy dandy chart, or a chair and we see that one mile equals

01:12

about one point six oh nine kilometers. all right then we'll you can take nine

01:16

point six five six right there plug that into our calculator and divide by one [equation]

01:21

point six oh nine to get just about six miles exactly. see how cleverly you could

01:26

give that problem there for you no extra charge. okay so from there with

01:30

you whatever else particularly problem asks of us whether it's asking for a

01:34

rate or time or whatever. so chew on that while you're chewing on your little Big

01:40

Mac. [man gets McDonald's meal]
