Adding and subtracting fractions 

Challenge yourself with the activities below. 

Remember the key steps:

  • make sure the denominator is the same on both fractions before adding or subtracting 
  • if the denominator is different then identify an equivalent fraction 

♫ "If adding or subtracting is your aim,
The bottom numbers must be the same!

♫ "Change the bottom using multiply or divide,
But the same to the top must be applied,

♫ "And don't forget to simplify,
Before its time to say good bye"
