Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

{Name[0][0]} has written $\displaystyle{\simplify{({a}x+{b})/({c}y+{d})}}$ in the equivalent form $\displaystyle{\simplify{({ar}x+{br})/({cr}y+{dr})}}$ .

What has {Name[0][0]} done to the first fraction in order to get the second? {Name[0][1]} has divided the top and bottom by Unnamed gap .
