Fractions, a la Shmoop. Have you ever run into the prickly situation
- 00:11
of having four people... and only one pizza? Or tried baking a cake that didn't turn out
- 00:16
so well because you put exactly one cup of everything into it?
- 00:20
It certainly would be wonderful if everything came out to a nice, even number, but our world
- 00:24
doesn't work that way. To communicate and make sense of all those

bits and pieces in between, we rely on -- "fractions". For example, if you just broke up with your
- 00:34
boyfriend, you are now half of one couple. It's okay though - he was a half-wit anyway.
- 00:41
Let's start by breaking down one of these suckers.
- 00:43
At least give it a half-hearted attempt. Up top you've got your numerator.
- 00:45
And downstairs is the denominator. The denominator tells us how many total pieces
- 00:50
make up the whole... While the numerator says how many of those
- 00:54
pieces we're talking about. So if your mother tells you that you can have
- 00:57
one-half of a pizza...
- 00:59
...she is saying that you can have ONE of the TWO pieces left over.
- 01:03
She also seems to care very little about your nutritional health.
- 01:05
You couldn't at least start with a salad?
- 01:07
Anyways, a fraction may also appear in the form of a Mixed Number, which is a combination
- 01:13
of a whole number and a fraction.
- 01:15
It's like getting a "two"-fer. For example, if you're baking Shmooperdoodle
- 01:19
cookies, you'll see clearly that it asks for two-and-three-fourths cups of chocolate chips.
- 01:24
Yeah, we love chocolate that much.
- 01:27
It's the same as eleven-fourths, but there's probably not a level for that on your measuring
- 01:31
cup. Anytime we get a fraction where the numerator
- 01:34
is larger than the denominator... ...we call them "improper fractions."
- 01:38
Just don't invite these improper guys to a fancy dinner party.
- 01:41
Fractions help us better communicate what we want, because they give us a larger math
- 01:45
vocabulary. Without them, every football game would be
- 01:48
only one "game" long... ...it would be impossible to fairly divide
- 01:52
food... ...and Fellini's classic film "8 ½" would
- 01:55
simply be called "8." In short, life would be more difficult...
- 01:59
and we would only be having a fraction of the fun.
