A fraction is a number that represents part of a whole.
Let's take a look at the shape below.
This circle is an example of a fraction model.
Note that
the entire circle represents one whole,
the circle has been split into equal parts, and
only part of the circle is shaded.
We can use the following fraction to represent the amount of circle that is shaded:
The two numbers that make up the fraction have special names:
The number on top of the fraction () is called the numerator. It represents the number of shaded parts.
The number on the bottom () is called the denominator. It represents the total number of parts.
What fraction of the shape is shaded?
There are parts of the shape in total, and parts are shaded.
Therefore, of the shape is shaded.
What fraction of the circle is shaded?
|

What fraction of the shape is shaded?
|
a
|
$\dfrac{7}{12}$ |
|
b
|
$\dfrac{7}{10}$ |
|
c
|
$\dfrac{5}{11}$ |
|
d
|
$\dfrac{12}{7}$ |
|
e

$\dfrac{10}{7}$ |
Which of the following shapes represents the fraction
Notice that means we must have parts in total, and only of them can be shaded.
Therefore, the correct shape is the following:
Which of the following shapes represents the fraction $\dfrac{1}{6}?$
|
a
|
|
|
