Fractions Flashcardizz

A fraction represents a part of a whole and is written as 'a/b', where 'a' is the numerator and 'b' is the denominator.

The numerator is the top number of a fraction and represents how many parts of the whole are being considered.

The denominator is the bottom number of a fraction and indicates the total number of equal parts the whole is divided into.

To multiply fractions, multiply the numerators together and the denominators together. For example, $$\frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}$$ .

$$\frac{7}{5}$$ .

To add fractions with the same denominator, add the numerators and keep the denominator the same. For example, $$\frac{a}{c} + \frac{b}{c} = \frac{a + b}{c}$$ .

$$\frac{8}{9}$$ .

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

$$\frac{12}{6}$$ or 2.

You use addition to combine parts of a whole.
