Dividing Fractions and Whole Numbers

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

To divide a fraction by a whole number, multiply the denominator of the fraction by the whole number. For example, $$\frac{1}{2} \div 4 = \frac{1}{2} \times \frac{1}{4} = \frac{1}{8}$$ .

Sharing equally means dividing something into equal parts so that each person gets the same amount.

Each friend gets $$\frac{1}{4}$$ of the pineapple.

Each friend gets $$\frac{1}{8}$$ of the pizza.

The result is 3.

To solve for n, multiply $$\frac{1}{4}$$ by the reciprocal of 3, which is $$\frac{1}{3}$$ . So, $$n = \frac{1}{4} \times \frac{1}{3} = \frac{1}{12}$$ .

The result is $$\frac{1}{16}$$ .

The reciprocal of a fraction $$\frac{a}{b}$$ is $$\frac{b}{a}$$ .

To convert a fraction to a decimal, divide the numerator by the denominator. For example, $$\frac{1}{4} = 1 \div 4 = 0.25$$ .
