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

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

To order fractions from least to greatest, convert them to have a common denominator or compare their decimal values.

A mixed number is a whole number combined with a fraction, such as 3 $$\frac{1}{2}$$ .

To convert an improper fraction to a mixed number, divide the numerator by the denominator and express the remainder as a fraction.

An equivalent fraction of $$\frac{2}{3}$$ is $$\frac{8}{12}$$ , obtained by multiplying both the numerator and denominator by 4.

The least common denominator is the smallest multiple that two or more denominators share.

To add fractions with different denominators, find the least common denominator, convert the fractions, and then add the numerators.

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