September Number Sense

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

The numerator is the top number in a fraction that indicates how many parts of the whole are being considered.

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

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

$$\frac{6}{15}$$ , which simplifies to $$\frac{2}{5}$$ .

Multiplication is the inverse operation of division. If $$a \times b = c$$ , then $$c \div b = a$$ .
