Welcome!Today, we'll explore fractions. You'll learn how to work with fractions, including simplifying, adding, subtracting, multiplying, and dividing them. Let's dive in!
What are fractions?Fractions are a way to represent parts of a whole. They consist of two numbers: the numerator (the top number) and the denominator (the bottom number). For example, in the fraction 3⁄4, 3 is the numerator, and 4 is the denominator.
Which of these represents a fraction?

Simplifying FractionsTo simplify a fraction, divide the numerator and denominator by their highest common factor (HCF). For instance, to simplify 12⁄16, divide both numbers by their HCF (which is 4). The simplified fraction is 3⁄4.

Adding and Subtracting FractionsTo add or subtract fractions, the denominators must be the same. If they are different, find the lowest common denominator (LCD), then convert the fractions to equivalent fractions with the same denominator before adding or subtracting.
What is the first step in adding fractions with different denominators?

Multiplying FractionsTo multiply fractions, simply multiply the numerators together and the denominators together. For example, 2⁄3 × 4⁄5 = 8⁄15.

Dividing FractionsTo divide fractions, multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping its numerator and denominator. For example, 2⁄3 ÷ 4⁄5 is the same as 2⁄3 × 5⁄4 = 10⁄12, which simplifies to 5⁄6.
