Meaning of a Fraction
A fraction represents a part of a whole object or a part of a collection of objects, written in the form of numerator and denominator.
Numerator and Denominator
The denominator shows the total number of equal parts the whole is divided into, while the numerator shows how many of those parts are taken.
Like and Unlike Fractions
Like fractions have the exact same denominators, whereas unlike fractions have different denominators.
Proper and Improper Fractions
A proper fraction has a smaller numerator than the denominator (value less than 1), while an improper fraction has a larger numerator than the denominator.
Mixed Fractions
A mixed fraction is a combination of a whole number and a proper fraction, such as 1 and 1/2.

Frequently Asked Questions
How do I know which number is the numerator and which is the denominator?
Remember that the denominator is down below (starts with 'd'), and the numerator is the number on top.
How do we add fractions with the same denominator?
You simply add the top numbers (numerators) together and keep the bottom number (denominator) exactly the same.
What is the difference between a proper and an improper fraction?
In a proper fraction, the top number is smaller than the bottom number. In an improper fraction, the top number is bigger than or equal to the bottom number.
