hey there it's Kaeleigh this lesson is on finding the fraction of a number if I
told you my pizza has 8 slices and I wanted to give you half of my pizza
how many pieces would you get so you would ask what is half of 8 and since
the fraction says 1 over 2 this tells me I'm dividing my pizza into two groups
now that I've divided my pizza into two even groups I can count how many slices
are in each group I count 1 2 3 4 you would give 4 slices
of pizza let's try another one this one is asking me what is 1/2 of 6
to help me I'm going to draw 6 candies now if I look at my fraction it says 1
over 2 so again this one tells me I'm going to make 2 even groups with my
candies and if I look at my fraction again I see a 1 on the top so I'm only
interested in how many candies are in one group so if I look at just one group
and I count my candies I see 1 2 3 so this tells me that 1/2 of 6 is 3 now
let's try a harder one this one asks what is 1/4 or 1/4 of 24 let's draw our
candies to help us think about this here are my 24 candies that's a lot of
candy I can look at my fraction and it says 1 over 4 so what is that asking me
well in real life I could have 24 candies and
or friends and I want to give my four friends each the same number of candy so
how many pieces would each friend get let's make our candies up into four
groups and see so now I have four even groups of candies for my four friends
but how many pieces of candy will each friend get I can just count how many
pieces are in one group one two three four five six each friend will get six
candies we can think about this in another way too when I say I am dividing
24 candies into four groups I mean I am dividing 24 by 4 and if you know your 4
fact families you might remember that 4 times 6 is 24 so 24 divided by 4 is 6 I
get the same answer 6 is 1/4 of 24 so this is a tricky one
it says what is 1/5 of 45 so that would mean I have to put 45 candies into 5
groups but remember dividing 45 into 5 groups is the same as just 45 divided by
5 and if you know your 5 fact families you might remember that 9 times 5 equals
45 so that means 45 divided by 5 is equal to 9 and that's an another way to
find my answer it'd be the same as if I took 45 candies and broke them into a
bunch of little groups I'd have 9 candies in each group it's a
great job you can practice what you've learned by
doing the online games and quizzes for a fraction of a number have fun and
remember to always be clever
