hello my name is Kylie and welcome to basic fractions identify fractions did
you know that you come across fractions in your daily life without even
realizing it probably in this video you'll learn to name read write and even
show fractions ready to take fractions apart
have you ever ordered pizza with your family and had to share with each person
often a pizza arrives already cut into equal parts like this one this whole
pizza is cut into parts or portions or fractions a fraction is part of a whole
a whole is something that is one piece like this whole pizza or this whole
cookie or this entire flower but when we talk about a fraction of the whole we
are talking about a slice a piece or a part like this flower petal a fraction
can also be a part of a whole set of things sets are a collection of similar
things example of sets are this box of crayons a set of marbles or a bunch of
jellybeans one crayon is a fraction of the set five marbles are a fraction of
the set and twelve jellybeans are just a fraction of the whole bag or the whole
set of jellybeans all of these show individual pieces of a set which is the
same thing as a fraction of a set when you bite into a fruit you are biting off
a fraction of the whole fruit you are actually eating fractions whoa remember
that pizza your family ordered it was already cut up into equal slices how
many slices do you see one two three four yes there are four slices or four
pieces or four parts that make up the whole pizza now what if you your mom and
your sister each take a slice how many pieces of the pizza are gone let's see 1
2 3 yes 3 out of 4 pieces of the pizza are eaten in math we have a special way
to say that 3 out of 4 pieces are eaten and that's with fractions to show that 3
out of 4 pieces are gone we write it like this we read this fraction as 3/4
or a fancy way to say it is 3/4 let's look at how to read and write fractions
more closely fractions are written in a special way you may have noticed that
the 3 is written at the top before at the
bottom and a small line separates the two numbers written in this way
represent or show a fraction the number in the top position has a special name
it's called the numerator the number in the bottom position also has a special
name it's called the denominator and the line going across is a fraction bar the
bottom number or the denominator tells how many parts the whole is divided or
cut into in this case the pizzeria delivered the pizza cut into four equal
parts the top number or the numerator tells how many pieces we have either
taken away or how many we've eaten in this case your family ate three in all
so we say three fourths or three quarters of this pizza was eaten by your
family cool isn't it let's look at more examples what fraction of this pizza is
eaten just by looking at it you can see that one half is gone and one half
remains since one piece out of two is eaten we write this fraction like this
there are two pieces and also we write two as the denominator and that's right
one piece is gone so we write the 1 as the numerator just like that what
fraction of this pie has been eaten hmm let's see there are three equal pieces
and two are eaten so we write the fraction like this 2 as the numerator
and 3 as the denominator when you read a fraction with a 3 at the bottom we call
it thirds in this case 2/3 of the pie is gone what fraction of this set of
marbles is colored blue there are six marbles in this set so we write 6 as the
denominator and five are colored blue so we write 5 as the numerator like this
cool ok so what if this rectangle represents a whole candy bar how would
we show that we're out of ten or four tenths we're
eating well since the denominator shows how many pieces in all and the numerator
shows how many pieces of the candy bar eaten we need to color in one two three
four pieces like this this shows or represents four out of ten or four
tenths as you can see fractions are all around
you as you keep an eye out for fractions in your daily life be sure to practice
what you learned in our fun online games and quizzes and remember to always be
