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

A fraction $$\frac{a}{b}$$ is greater than $$\frac{c}{d}$$ if the value of $$\frac{a}{b}$$ is larger than the value of $$\frac{c}{d}$$ .

To compare fractions with different denominators, convert them to equivalent fractions with a common denominator or convert them to decimal form.

$$\frac{2}{10} = \frac{1}{5}$$ .

They are equal: $$\frac{3}{6} = \frac{1}{2}$$ .

$$\frac{4}{8} = \frac{1}{2}$$ .

Any fraction with a numerator less than 3 and a denominator greater than 7 will be less than $$\frac{3}{7}$$ .

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

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

Two fractions are equivalent if they represent the same value, such as $$\frac{2}{4}$$ and $$\frac{1}{2}$$ .
