Why is there an apostrophe in my formulae? Watch

1. 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.

2. 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 and you need to find y when x=3/2.

So simplify

Oh wow. I didn't even notice how all the others had the same thing. Thank you very much.

No problem at all! Glad to have helped
8. 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

10. 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.
12. Oh you are intelligent. I wish I got this. Thank you again, all.

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.

This is quite possibly my all time favourite TSR post.
