What is a common denominator?

A common denominator is a shared multiple of the denominators of two or more fractions. It is used to add or subtract fractions.

How do you find a common denominator for two fractions?

To find a common denominator, identify the least common multiple (LCM) of the denominators. For example, for $$\frac{1}{4}$$ and $$\frac{1}{16}$$ , the LCM is 16.

What is the quotient of two fractions?

The quotient of two fractions is the result of dividing one fraction by another. For example, $$\frac{3}{4} \text{ divided by } \frac{1}{2} = \frac{3}{4} \times \frac{2}{1} = \frac{3 \times 2}{4 \times 1} = \frac{6}{4} = \frac{3}{2}$$ .

What does it mean to multiply fractions?

To multiply fractions, multiply the numerators together and the denominators together. For example, $$\frac{2}{3} \times \frac{3}{4} = \frac{2 \times 3}{3 \times 4} = \frac{6}{12} = \frac{1}{2}$$ .

A fraction represents a part of a whole and consists of a numerator (top number) and a denominator (bottom number). For example, $$\frac{1}{2}$$ represents one part out of two equal parts.

How do you add fractions with different denominators?

To add fractions with different denominators, first find a common denominator, convert the fractions, and then add the numerators. For example, $$\frac{1}{4} + \frac{1}{16} = \frac{4}{16} + \frac{1}{16} = \frac{5}{16}$$ .

What is a mixed number?

A mixed number is a whole number combined with a proper fraction, such as $$2 \frac{1}{4}$$ .

How do you convert an improper fraction back 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 numerator of the proper fraction. For example, $$\frac{23}{4} = 5 \frac{3}{4}$$ .
