Yeah I know cross multiplying It just doesn't get the correct answer

Divide throughout by 100.

Get both fraction over a common denominator.

Yes!
Where have you got so far? Which part of your working are you stuck at?

Well ... subtract then ... but that is just adding a negative so my post holds

9. I have learnt how to do it thanks! I just cross multiply it! I accidently put the x and 5 wrong way, so I was mixed up. Sorry!

No please, it's fine. In my case I really do need the solution, it doesn't matter, because I have the mark scheme, I just need clarification on it. So please don't remove next time! Thanks!

Thank you!
All you have to do is follow raheem94's solution line-for-line, but changing the numbers as appropriate, and you'll get your answer. If you're still stuck, show your working and we'll help you get there. It won't take much work to do this, but you'll learn much more from it than you would from copying out a solution line-for-line without having to think about it at all.

Sorry for you getting a neg rep for abiding with the laws, the rep system is flawed in my opinion.

People are welcome to give me neg rep if they think I've done something wrong. (If anything, rep whether pos or neg will help me work out whether or not I'm screwing up this newfangled 'moderator' thing or not!)

But in this case I'm quite sure of my position: the full solution, albeit correct, was a cop-out for the OP and undermined the effort that other users had put into trying to help the OP actually develop maths skills rather than copying-out skills.

But your neg rep was undeserved. It won't allow me to +rep you to cancel that out.

By the way, congrats for becoming a moderator!
