Understanding Fraction Addition

Adding fractions is a fundamental mathematical operation. The process varies depending on whether the fractions have the same or different denominators.

Same Denominators

When fractions have the same denominator, simply add the numerators and keep the denominator:

a/c + b/c = (a+b)/c

Example: 1/4 + 3/4 = (1+3)/4 = 4/4 = 1

Different Denominators

When fractions have different denominators, convert them to equivalent fractions with a common denominator:

a/b + c/d = (ad)/(bd) + (bc)/(bd) = (ad+bc)/(bd)

Example: 1/2 + 1/3 = (3/6) + (2/6) = 5/6

For efficiency, use the least common multiple (LCM) of the denominators instead of simply multiplying them.

Mixed Numbers

When adding mixed numbers (whole + fraction):

  1. Add the whole number parts
  2. Add the fraction parts
  3. Convert any improper fraction to a mixed number and adjust the whole part accordingly

Example: 2 1/4 + 3 1/3 = (2 + 3) + (1/4 + 1/3) = 5 + (3/12 + 4/12) = 5 + 7/12 = 5 7/12

Adding Fractions Formula:
a/b + c/d = (ad + bc) / bd
