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

What is the product of $$\frac{1}{2}$$ and $$\frac{3}{4}$$ ?

The product is $$\frac{1 \times 3}{2 \times 4} = \frac{3}{8}$$ .

If $$\frac{3}{5} \times n = \frac{9}{25}$$ , what is n?

To find n, divide $$\frac{9}{25}$$ by $$\frac{3}{5}$$ : n = $$\frac{9}{25} \div \frac{3}{5} = \frac{9}{25} \times \frac{5}{3} = \frac{9 \times 5}{25 \times 3} = \frac{45}{75} = \frac{3}{5}$$ .

What is the result of multiplying a fraction by 1?

Multiplying any fraction by 1 does not change its value. For example, $$\frac{2}{3} \times 1 = \frac{2}{3}$$ .

What is a mixed number?

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

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 over the original denominator.

If $$\frac{4}{5} \times n = \frac{4}{15}$$ , what is n?

To find n, divide $$\frac{4}{15}$$ by $$\frac{4}{5}$$ : n = $$\frac{4}{15} \div \frac{4}{5} = \frac{4}{15} \times \frac{5}{4} = \frac{5}{15} = \frac{1}{3}$$ .

What is the relationship between multiplication and division of fractions?

Multiplication of fractions can be used to find a missing factor, while division of fractions involves multiplying by the reciprocal.

If $$\frac{3}{4} \times n = \frac{24}{12}$$ , what is n?

To find n, divide $$\frac{24}{12}$$ by $$\frac{3}{4}$$ : n = $$\frac{24}{12} \div \frac{3}{4} = \frac{24}{12} \times \frac{4}{3} = \frac{24 \times 4}{12 \times 3} = \frac{96}{36} = \frac{8}{3}$$ .

What is the importance of finding a common denominator when adding or subtracting fractions?

Finding a common denominator allows you to combine fractions easily, ensuring that the parts being added or subtracted are equivalent.

What does it mean for fractions to be equivalent?

Equivalent fractions are different fractions that represent the same value, such as $$\frac{1}{2}$$ and $$\frac{2}{4}$$ .
