In today’s lesson we will be adding and subtracting fractions with different denominators. This is something that you have done multiple times in previous year groups and therefore this lesson should just be a revision lesson to remind yourself of the rules. Remember that to add or subtract the fractions, the denominators must be the same (this might involve you finding some equivalent fractions).
Once you have the denominators the same, you then complete your addition or your subtraction. The denominator now stays the same – only the numerators are added or subtracted from one another.
