Dividing Fractions
Look at this word problem:
Let’s visualise the fraction
problem using a bar model to
understand how to solve it.
Dividing Fractions
Next, we are told that Lauren is
sharing the chocolate between five
friends. We can divide the bar
horizontally to represent this.
Whole bar of chocolate
Number of
friends sharing
the chocolate
Chocolate to be shared
Dividing Fractions
Now, when we combine these two bar models, we will be able to see how
much of the shared chocolate each friend gets:
Method
We now know that solving the word problem involves dividing a proper fraction
by a whole number. If we want to, we can use the fraction rules to find the
answer without drawing the bars.
1
Change the whole number into a fraction.
2
Change the division sign to a multiplication sign.
3
Invert (flip) the second fraction.
4
Multiply the numerators together.
5
Multiply the denominators together.
6
If necessary, simplify the answer by dividing by
the greatest common factor.
