Dividing algebraic fractions

• Never?try to divide fractions
• Instead?“flip’n’times”
• So “÷a/b” becomes “×b/a”and then follow the rules for multiplying…

Multiplying algebraic fractions

1. Simplify?by factorising and cancelling (ignore the × between the fractions)
2. Multiply the?tops?(numerators)
3. Multiply the?bottoms?(denominators)
4. Simplify?by factorising and cancelling (if you missed something earlier).
