“Why can’t I just add the top and bottom numbers?”
A useful explanation starts with the size of the pieces, then gives you a chance to try the next step.
¾ + ⅛ = ?
- Make the pieces the same size.Fourths and eighths are different units. Rewrite ¾ as 6 eighths: 6/8.
- Add the matching pieces.6/8 + 1/8 = 7/8. The denominator stays 8 because the pieces are still eighths.
- Try a new question yourself.Work out ½ + ¼. Explain how you chose the denominator before checking your answer.
