Fractions on a number line

A fraction represents a part of a whole. It is written as $$\frac{a}{b}$$ , where 'a' is the numerator (the part) and 'b' is the denominator (the whole).

The numerator is the top number in a fraction. It shows how many parts we have.

The denominator is the bottom number in a fraction. It shows how many equal parts the whole is divided into.

To represent $$\frac{1}{2}$$ on a number line, find the midpoint between 0 and 1.

An improper fraction is a fraction where the numerator is greater than or equal to the denominator, like $$\frac{5}{4}$$ .

A proper fraction is a fraction where the numerator is less than the denominator, like $$\frac{3}{4}$$ .

Divide the numerator by the denominator. The quotient is the whole number, and the remainder is the new numerator.

A mixed number is a whole number combined with a proper fraction, like 1 $$\frac{1}{2}$$ .

Add the numerators and keep the same denominator. For example, $$\frac{1}{4} + \frac{2}{4} = \frac{3}{4}$$ .

Find a common denominator, convert the fractions, then add the numerators.
