A fraction represents a part of a whole and is written as numerator divided by denominator.
When adding fractions with different denominators, use the formula:
a/b + c/d = (ad + bc) / bd
Subtract fractions by converting them to a common denominator.
a/b − c/d = (ad − bc) / bd
Multiply numerators together and denominators together.
a/b × c/d = ac / bd
Division of fractions is done by multiplying by the reciprocal.
a/b ÷ c/d = ad / bc
