Revision - Algebraic Fractions II Numerical and Algebraic Fraction Operations. By I Porter Multiplication & Division

Card2 Numerical Operation Revision MultiplicationDivision Evaluate Alternate by factorising first Multiply numerators then multiply the denominators Factorise and reduce Multiply numerators then multiply the denominators To divide by a fraction, you multiply by it’s reciprocal. Algebraic fraction are simplified by the same processes, but you should first factorise numerator and denominator cancel any common factors in the numerator and denominator.

Card3 Simple Algebraic Fractions Examples: Simplify the following Factorise numerator and denominator Cancel common factors in numerator and denominator a) b) Factorise numerator and denominator Cancel common factors in numerator and denominator c) Factorise numerators and denominators Cancel common factors in numerator and denominator Multiply numerators and denominators

Card4 Examples: Simplify the following a) Multiply by the reciprocal Factorise numerators and denominators Cancel common Factors. b) Multiply by the reciprocal Factorise numerators and denominators Cancel common Factors.

Card5 Simplification of Algebraic Fractions by Multiplication and Division. Change ÷ by x by reciprocal of divisor. Factorise the numerators and denominators. Cancel out matching factors from numerator and denominators. Multiply Numerators, then multiply Denominators as FACTORS (…)(…). Exercise: Simplify the following
