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.

Ergh. Could you give me some of these type of questions please. Like about 5 so I can work on them?

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

Try 6.54, 8.68, 1.21, 10.65.

Is this correct now?

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.

Yeah the answers are correct. Your lines of working out doesn't make sense though at all because you say 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 wrong Woking out please on fractions.

I tried correcting this

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