A fraction represents a part of a whole and consists of a numerator (top number) and a denominator (bottom number). For example, in the fraction $$\frac{3}{4}$$ , 3 is the numerator and 4 is the denominator.

What does it mean to simplify a fraction?

Simplifying a fraction means reducing it to its lowest terms, where the numerator and denominator have no common factors other than 1. For example, $$\frac{4}{8} = \frac{1}{2}$$ .

What is the lowest terms of a fraction?

A fraction is in lowest terms when the numerator and denominator are as small as possible. For example, $$\frac{6}{9}$$ simplifies to $$\frac{2}{3}$$ .

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

To convert a mixed number to an improper fraction, multiply the whole number by the denominator and add the numerator. For example, $$2\frac{1}{3} = \frac{2 \times 3 + 1}{3} = \frac{7}{3}$$ .

What is the sum of $$\frac{1}{2} + \frac{1}{4}$$ ?

The sum is $$\frac{1}{2} + \frac{1}{4} = \frac{2}{4} + \frac{1}{4} = \frac{3}{4}$$ .

What is the product of $$\frac{2}{5} \times \frac{3}{4}$$ ?

The product is $$\frac{2 \times 3}{5 \times 4} = \frac{6}{20} = \frac{3}{10}$$ after simplifying.

How do you find a common denominator?

To find a common denominator, identify the least common multiple (LCM) of the denominators. For example, for $$\frac{1}{3}$$ and $$\frac{1}{4}$$ , the LCM is 12.

What is the difference between a proper fraction and an improper fraction?

A proper fraction has a numerator smaller than the denominator (e.g., $$\frac{3}{4}$$ ), while an improper fraction has a numerator larger than or equal to the denominator (e.g., $$\frac{5}{4}$$ ).
