00:00well fun fun fun today we are going to learn about fractions well as we
00:08mentioned earlier today we are going to learn about fractions fractions are so
00:13awesome and so much fun all right well let's start here what is a fraction when
00:21we say the word fraction what do we mean what is a fraction well a fraction is
00:29something that shows parts of a whole let's say there's this lady named Cindy
00:39Cindy has a pizza which is great she loves pizza so yummy pizza but then her
00:49friend Chomsky arrives you remember Chomsky Chomsky likes pizza too and he's
00:54a little bit hungry so maybe Cindy isn't gonna eat the whole pizza now maybe
00:59they're gonna split it what do you think so they split the pizza in half each of
01:07them get one half of the pizza that neat then everyone has pizza each of them
01:14have one half of the pizza they split it right down the middle now remember a
01:22fraction is something that shows parts of a whole so here is what the fraction
01:29looks like a one a line and the two that is the fraction one half each of them
01:37Cindy and Chomsky get one half of the pizza so this is one half it's a very
01:47important fraction because we use it all the time now you might be wondering what
01:53do the numbers mean and how does it show one half well the bottom number shows
02:01the total number of parts the top number shows how many parts we are talking
02:10about pretty simple let's go back to our example there are a total of two
02:20parts to the pizza so there's a two on the bottom and Cindy just gets one part
02:27that's the part we're talking about so Cindy gets just one half of the pizza
02:32she doesn't get the whole thing she gets just one part she gets one half the
02:40bottom number of a fraction is called the denominator the denominator is the
02:46total number of parts the top number is called the numerator the numerator tells
02:56us how many parts we are talking about in this case Cindy is having one part of
03:02the pizza the other part of course is going to Chomsky let's try this let's
03:10say there's another pizza and this pizza has four parts the number four is
03:16the denominator because there are four pieces of pizza four parts let's say
03:27Kelly shows up and wants to have one part of the pizza one piece of the pizza
03:35the numerator or the top number of the fraction is the number one because Kelly
03:43is having one part or one piece of the pizza Kelly is having one-fourth of the
03:52pizza pretty simple pretty fun fractions are awesome now we're gonna need your
04:01help help us figure out what fraction is it huh what fraction is it wow we're
04:10gonna have a great time let's say we have a group of five sports balls one is
04:19a basketball the other four are soccer balls let's figure out what fraction of
04:28the balls are basketballs what fraction of the balls are basketballs so we know
04:40a fraction has a line in the middle and the top number is the numerator and the
04:44bottom number is the denominator the denominator shows us the total number of
04:52parts or units how many sports balls are there yeah five five is the
05:03denominator good job now remember we're asking for the fraction of sports balls
05:10that are basketballs so how many basketballs are there yeah just one the
05:21number one is the numerator so one-fifth of the sports balls are
05:28basketballs one-fifth great job let's try this final example let's say there
05:37are five pets five pets two of them are dogs and three of them are cats what
05:49fraction of the pets are cats huh that's a good question what fraction of
05:55the pets are cats remember here's what a fraction looks like it's got a line in
06:02the middle with the top number being the numerator and the bottom number is the
06:07denominator so the total number of pets is five what number is the denominator
06:18what number goes on the bottom yeah five five is the denominator it tells us
06:26the total number of pets remember we're asking for the fraction of the pets that
06:35are cats how many cats are there yeah three so what's the numerator yeah three
06:47three is the numerator three-fifths of the pets are cats wow that was so cool
06:59but none of those cats are as special to me as you mr. whiskers not even a
07:05fraction of my heart belongs to my whole heart I love you mr. whiskers a fraction
07:15is something that shows parts of a whole the top number of a fraction is
07:24the numerator how many parts we are talking about and the bottom number of a
07:29fraction is the denominator the total number of parts
