about form 1 & 2(karyaw's class)

Kar Yaw here...reporting in xD

form 1

1st of all I did help them revise about the last week that I taught them about the percentage

and remind them

the UNIVERSAL FORMULA: New price - Old price(difference in price)

____________________________ X 100 %

Old price (original price)

then this week before I gave them the exercise to do:

I asked them to have a look and know the formula for the five formula:

There are:

1. profit

2. discount

3. simple interest

4. dividend

5. commission

so I asked them one-by-one whether they understand for the 5 of them a not...

and almost all the class don't know for dividend and commission

so I did use examples to explain to them each..

for dividend:

as a example is...

now I am interest in KFC and invest to it

let say this month they earn 1mil of profit by selling chicken(as here I explain profit too) xD

and now let say this company have 7 boss include me..

so we all 7 together to divide the profit money we earn.. ^^

and now till the commission o

example:

now I am a promoter which help Nike work

let say my salary ONLY got RM 300

and now I sell one nike shoes I get RM 20 for each pairs I sold out

if this month I sold out 100 pairs so means I get RM2000 for my commision

so do you all understand now?

then we started to do the percentage exercise which have 10 ques..is quite hard de! xD

need use the 5 formula above!

THAT'S ALL FOR THAT! XD

form 2

1st of all is the same...revised for last week what i had taught

about the two quantities

after that, I continue for the ratios in three quantities...

so I told them is as easy as the last week you all learn

is just that this week got new friend coming in

means got 3 quantities

OK! lets say last week is about A:B but this week is about A:B:C

is just easy that your grandmother also know how to do*evil laugh* hahahahah xD

so continue and I remind them in ratio the quantities must be same only can take off

then also remind that even the ratio how much bigger or times how much..all must be the same

let says that is the ratio A:B=2:3

B:C=4:8

therefore you need to write out the 3 ratios, A:B:C

2:3 (so now u need to do is balance where

4:8 both sides also have no) there4 is B

_________ so 3 need to x4 and 4 need to x3

8 :12:24 so is balance now and now 8x3

2x4

so now u get 8:12:24

remember ratios need to get the lowest form...

so you get is by using the factors or 8, 12 and 24

use 4 to divide each and get 2:3:6

(TAKE NOTE: the simplify number must be a factor no for all of the number!)

and now is about the m:n:o = 2:3:4

and M+N+O= 900

so find M=? , N=?, O=?

1. see the ques and understand it!
2. so now u know that it want to find for each
3. so did u see is M+N+O
4. so u know that need use the ratio add together and find the average number
5. total of ratio get 2+3+4= 9
6. give unknown to represent your average number as long didnt same as ur ques
7. so now 9x=900
8. so ur average number get x=100
9. so now u time one by one M=100x2=200
10. N= 100x3=300
11. O=100x4=400
12. can u see that..total of that is still 900. ( to check ur answer)

and next one is about the minus for as same above that one..just change to minus..

the way to do is still the same o xD

thats all for my class ba!

THANKS ALOT! xD
