- A fraction is a number representing a part of a whole or is an operation on
a number. The whole may be a single object or a group of objects.
- When expressing a situation of counting parts to write a fraction, it must
be ensured that all parts are equal.
- In 5/7, 5 is called the numerator and 7 is called the denominator. Denominator
and numerator can be identified for any fraction.
- Fractions can be shown on a number line. Any fraction has a point associated
with it on the number line.
- In a proper fraction, the numerator is less than the denominator. The fractions,
where the numerator is bigger than the denominator are called improper fractions.
Improper fraction can be written as a combination of a whole and a part, and
are then called mixed fractions.
- Two fractions are said to be equivalent if they represent the same quantity. Each
proper or improper fraction has infinite equivalent fractions. To find an equivalent
fraction of a given fraction, we may multiply or divide both the numerator and
the denominator of the given fraction by the same number.
- A fraction is said to be in the simplest (or lowest) form if its numerator and the
denominator have no common factor except 1.
