    No worries, it happens to the best of us

    I would be slightly concerned however. If it were the other way round (eg 24/45 is simplified to 8/15) then it'd be fine, they've just simplified, but if they are listing 24/45 as the answer and you get 8/15 then you should be getting 24/45 off the bat, unless you did get it and then simplify it but I'm not sure if this is the case here.

    You're right :/ I'm not sure if it may be because I multiplied my denominator out instead of using the quotient rule? It's a bit weird. Hang on I'll post my working out
