A fraction represents a part of a whole. It consists of a numerator (top number) and a denominator (bottom number). For example, in the fraction $$\frac{1}{2}$$ , 1 is the part and 2 is the whole.

What is the reciprocal of a fraction?

The reciprocal of a fraction is obtained by flipping the numerator and denominator. For example, the reciprocal of $$\frac{3}{4}$$ is $$\frac{4}{3}$$ .

How do you simplify a fraction?

To simplify a fraction, divide the numerator and the denominator by their greatest common divisor (GCD). For example, $$\frac{8}{12} = \frac{2}{3}$$ after dividing both by 4.

What is a mixed number?

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

How do you convert an improper fraction to a mixed number?

To convert an improper fraction to a mixed number, divide the numerator by the denominator. The quotient is the whole number, and the remainder is the new numerator. For example, $$\frac{9}{4} = 2 \frac{1}{4}$$ .

What is the least common denominator (LCD)?

The least common denominator is the smallest number that can be used as a common denominator for two or more fractions. For example, the LCD of $$\frac{1}{3}$$ and $$\frac{1}{4}$$ is 12.

How do you add fractions with different denominators?

To add fractions with different denominators, first find the least common denominator (LCD), convert the fractions to equivalent fractions with the LCD, and then add the numerators. For example, $$\frac{1}{3} + \frac{1}{4} = \frac{4}{12} + \frac{3}{12} = \frac{7}{12}$$ .

What is a proper fraction?

A proper fraction is a fraction where the numerator is less than the denominator. For example, $$\frac{2}{5}$$ is a proper fraction.
