To add fractions, you need to find a common denominator, then add the numerators while keeping the denominator the same. For example, to add 1/2 + 1/4, first find a common denominator (4), convert the fractions (2/4 + 1/4), then add the numerators (3/4).

To subtract fractions, find a common denominator, then subtract the numerators while keeping the denominator the same. For example, to subtract 3/4 – 1/2, first find a common denominator (4), convert the fractions (3/4 – 2/4), then subtract the numerators (1/4).

To multiply fractions, multiply the numerators together and the denominators together. For example, to multiply 1/2 × 3/4, multiply the numerators (1 × 3 = 3) and the denominators (2 × 4 = 8), resulting in 3/8.

To divide fractions, multiply the first fraction by the reciprocal of the second fraction. For example, to divide 1/2 ÷ 1/4, multiply 1/2 by the reciprocal of 1/4, which is 4/1, resulting in (1/2) × (4/1) = 4/2 = 2.

To simplify a fraction, find the greatest common divisor (GCD) of the numerator and denominator, then divide both by that number. For example, to simplify 4/8, find the GCD of 4 and 8, which is 4, then divide both by 4 to get 1/2.
