S4 Prelims
Published November 16th, 2006 in 4Y2, PrelimsJust a small good luck to my wonderful S4 class. I hope your exams go well next week. If you have any problems you wish to ask me about, please comment on this post and I’ll try and answer your problems during the weekend.
hey just testin i got here succesfully
Hi i managed to get it to work! no problems yet!
Excellent Rebecca. Welcome to the community. You are the first S4 pupil to join. Congratulations. Any questions about revision, please don’t hesistate to ask. Mr S.
revising gradient. question 7a on page 12. copy and complete this table for y=1/3x when x= -4,-2 etc. hopeless on fractions and things any help anyone please?
Hey. I know this isn’t really my blog but maybe I can help
The equation y=1/3x means that y is a third of whatever x is. That means that if x is 6, y is 2. If x is 9, y is 3… and so on.
It’s easier if you use a table where all the y values are multiples of three, e.g. 6,9,12,15 etc as these are all easy to find a third of.
However if you have to find a third of -4, think about it like this… if 4 mince pies are divided equally amonst 3 people, each person gets 1 pie, plus a third of the leftover pie, i.e. one and a third.
So if y=1/3x (”y is a third of x”) and x=-4, y is negative one and one third.
Hope that helps. This would be a lot easier to explain with a diagram. Sorry for jumping into your weblog stebbo… just wanted to try out a reply! Hope you don’t mind
well yes, thnkyou very much for your help. but on the answer page it says tht 1/3 of -4 is = to -3. i think perhaps it is wrong. i am very confused. am i being really stupid? but thankyou timschmitz
hi. me again. i also have this question which i am finding tricky:Jill uses 240g of flour, 60g margerine, 30g sugar and 150 ml milk to make 8 scones. How much of each will she need to make 12 scones? ( question 5 on page 31 )
Hi Tim and Emily. Nice to see one of my colleagues helping us out isn’t it Emily. His explanation hopefully helped you. It looks as if the answer to the question you are doing is wrong in the book. You know that you’re not being stupid. Any more problems post away. I’ll check in regularly from now until late today. Thanks again Tim. I as well as Emily really do appreciate it.
Sorry Emily you commented as I was commenting back to you. There are a couple of ways of doing this question.
1 Jill knows the amount of each ingredient it takes for 8 scones. She needs 4 more so you could work out how much of each ingredient by finding the relevant fraction of the eight scones that she will need to make the extra scones(i’m not telling as it may give too much away.) Then add on the relevant amounts of each ingredient to the amounts given.
2. A more practical way is to find how much of each ingredient it takes for one scone. This involves finding a fraction of the amounts of each ingredient again. This way then allows you to multiply each ingredient for any number of scones you may wish to bake. ie if you want 8 multiply by 8. If you want 12 multiply by 12.
I hope this makes sense. I have tried to leave some work for you to reason. Please post back if you don’t understand what I said and I’ll help you more Emily
thnks problem solved
Just testing this thing out!
You’ve joined us Nick. I hope you’ll ask for help if you need it. Please feel free to help out anyone else if you can. Remember we’re all in this together. Good luck tomorrow if I don’t see you before the Prelim.
Hello, just seeing if this works!
Hey Karen. Nice to see you. It surely does. Look at how busy my higher class have been tonight. I hope you guys will be the same after the prelims. Welcoem to the world of Stebblog.
