    Hi. I'm new to maths... And I need help on a simple fraction.

    How do I answer question f? (See attached image).
    How do I multiply x by an apostrophe?
    I don't get it.

    Am trying to self study maths A level and am struggling at the first hurdle. Eeeeek.

    Is it not a comma? Just separating the y = ... from the x = ...

    I think we need to see all of the question to help you with this.

    Could you post a picture of all of question 6?

    That's two equations separated by a comma, not a single equation.

    I'm guessing that you need to work out y in its simplest for a particular value of x.

    in (f) you have y=\frac{6}{5x} and you need to find y when x=3/2.

    So simplify \frac{6}{5 \times \frac{3}{2}}

    So, how likely is it that my text book has a misprint?

    6/5x where x = 3/2

    6 x 3 = 18
    5 x 2 = 10

    = 18/10 = 1 4/5

    The book's answer to the above equation is 4/5.

    But my answer is 18/10 or 1 4/5 simplified.

    Where am I going wrong?

    You are calculating \dfrac{6}{5}x

    The question asked for \dfrac{6}{5x}

    You would multiply 5 by 3/2 because it's 5x on the bottom, right? That would give you 15/2, you'd have 6 on the top, over 15/2, then multiply both parts by 2 to get rid of the fraction on the bottom, giving 12/15, then simplify it to 4/5

    The book is correct

    I don't know what you're trying to do but you should be working out 5x = 15/2 and then working out 6 divided by this.

    It's an easy mistake to make.

    I remember when I was learning about scatter graphs, and I thought it said "s catter graphs" and I was so confused why it was called that.
