Gap-fill
Ask the student a question, and give any hints about how they should answer this part.
We want to find:
| {num1simp} | + | {num2simp} |
| {denom1simp} | {denom2simp} |
We need to write the fractions with the same "denominator" (the number on the bottom).
What's the smallest number that divides by {denom1simp} and {denom2simp} (the "lowest common multiple")?
Answer: the lowest common multiple of {denom1simp} and {denom2simp} =
