    For 5 you multiplied the numerator by 100 but the denominator by 1000? Pick one or the other; can't do both
    What do you mean?

    165/1000 = 0.165. NOT 1.65.

    You did the same mistake on Q6.

    Well think about it. What did you multiply 1.65 by to get 165? Multiply the denominator by the same number

    Why are you ignoring the denominator...? What you've written would imply that 1.65=165 which is not true.

    I really don't understand this.
    I think I need an example.

    You've done this exact same process before.

    \frac{1.65}{1}=\frac{1.65}{1} \cdot \frac{100}{100}=\frac{165}{100}

    proceed to simplify.

    Where does 100/100 come from?

    I did those questions like this

    I followed this

    Yeah the answers are correct. Your lines of working out doesn't make sense though at all because you say 10.68=\frac{10.68}{100}=\frac{10  0}{100} which just makes me go like "nope nope nope, maths is broken here" because they're NOT equal.

    100/100 is just there to show you how the numerator and denominator change. 100/100 is equal to 1 (makes sense, the overall value doesn't change if you multiply by 1) and so you proceed to multiply the numerators and denominators respectively.

    Could you do a few questions please with the correct working out? On paper

    On fractions? Or on quadratics like you've posted above?

    The quadratic looks good. Though a=1 where you list a, b and c.
