Madison is going to share this
chocolate bar with her seven friends. There are what squares in
total. Each person will get what square or
squares of chocolate. Find the denominator. Each person will get one what of
the chocolate bar.
We’re shown a picture of a
chocolate bar. And we’re told that Madison is
going to share this bar with her friends. Now, we’re told the number of
friends that she’s going to share it with is seven. So, if we include Madison, because
she’s sharing it, that’s eight people together, isn’t it? Now, this question is all about
fractions. And fractions are special numbers
that help us to show part of a whole. And as Madison is going to be
splitting up this chocolate bar into different parts, a fraction is a good way to
describe it, isn’t it?
Now, to help us think about what
fractions we can see, we’ve got some sentences to complete. And the first one is about the
number of squares that there are in the chocolate bar altogether. There are what squares in
total. Let’s count them. One, two, three, four, five, six,
seven, eight. There are eight squares in
total. This is quite useful, isn’t it? Remember how many people that
Madison wanted to share her chocolate bar between. It was eight, wasn’t it? So, she has eight squares, and she
wants to share them between eight people.
Onto our second sentence. Each person will get what square or
squares of chocolate. Well, we know if there are eight
squares and Madison wants to share them between eight people, everyone’s going to
get one square each. Each person will get one square of
chocolate.
Now, we can use the information
that we’ve been given to work out what fraction of the chocolate bar each person
gets. Each person will get one what of
the chocolate bar. This number here is our
fraction. There are two numbers, and there’s
a line in between. The top number or the numerator in
a fraction tells us the number of parts that we’re talking about. And we know that each person is
going to get one part of the chocolate bar or one square. That’s where this number one comes
from on the top.
But the denominator or the bottom
number in this fraction is missing. The denominator shows us the number
of equal parts that the whole amount has been split into. In other words, each person will
get one out of how many? Can you see the sentence that’s
gonna help us with this? We found the denominator when we
added up the number of squares there were in total. There were eight, weren’t
there? Each person will get one out of
eight squares. And we read this fraction as
one-eighth.
If Madison is going to share this
chocolate bar with her seven friends, we worked out that was eight people
altogether. There are eight squares in
total. And because there are eight people,
we know each person will get one square of chocolate. And so, we can say each person will
get one-eighth of the chocolate bar.
