How do I add fractions with different denominators?

Find the least common denominator (LCD), convert each fraction to have that denominator, then add the numerators. For example: 1/3 + 1/4 = 4/12 + 3/12 = 7/12.

How do I simplify a fraction?

Divide both the numerator and denominator by their Greatest Common Divisor (GCD). For example, 8/12: GCD is 4, so 8÷4 / 12÷4 = 2/3.

How do I divide fractions?

Flip the second fraction (take its reciprocal) and multiply. For example: 2/3 ÷ 1/4 = 2/3 × 4/1 = 8/3.

What is a mixed number?

A mixed number combines a whole number with a fraction, like 2⅓. It represents 2 + 1/3 = 7/3 as an improper fraction.
