Q&A - P3 Math

Daddy:

Hi,


I have a math question need help?

\"Mrs Wong was short of $42 if she bought 5 similiar vases. So she bought 3 such vases and has $12 left. What was the cost of each vase?\"

Thankss.
Daddy :?

Hi daddy,

For every 2 less vases Mrs Wong buys, she will save ($42 + $12) = $54
So, for every 1 less vase she buys, she saves $54/2 = $27 (this is the cost of 1 vase)

HI,


My daughter go to P5 next year. I heard some parents said they need to study Foundation math, and it is important subject.
I do not know what is this. Is it difficult than normal math they currently study now?
Any recommended good book on foundation math? Thanks.

hi,
Foundation Math is actually supposed to be easier than Standard Math as they cater to weaker students. You can read more here...

Hi,


I read through the thread. Those who passed 2 subjects or less
Your child will be recommended to take (in P5) either 3 standard subjects + 1 other foundation.

But the principle of my daughter is in insists that all students take foundation math regardless of all or less subjects passed.

May be this school more kiasu abit. :lol:

Thanks jedamum for the info...

"There is a total of 240 Malay and Chinese pupils in a school. 1/4 of the Chinese pupils and 1/2 of the Malay pupils are girls. There is an equal number of Malay as Chinese boys. How many more Malay than Chinese pupils are there in the school?"

Thanks.

Let Chinese be 4U
Let Malay be 2V

Chinese Boys will be 3U
Malay Boys will be 1V

Equal no. of Malay boys and Chinese boys means 1V = 3U

Total Malay = 2V = 6U

Total students = 6U + 4U = 240 and I think you can work out the rest.

Hi Daddy, the working is like this:

If 1/4 of the Chinese are girls, 3/4 are boys.
\" 1/2 \" \" Malay \" \" 1/2 \" \"

So 3/6 (1/2) of the M boys equals 3/4 of the C boys, so the ratio of M pupils to C pupils is:

M : C
6 : 4

6u + 4u = 10u

10u is 240 so 1u is 24

24 X (6-4) = 48.

Hi Muffin,


{If 1/4 of the Chinese are girls, 3/4 are boys.
\" 1/2 \" \" Malay \" \" 1/2 \" \" } this I understood.

How about this:
So 3/6 (1/2) of the M boys equals 3/4 of the C boys, so the ratio of M pupils to C pupils is:
M : C
6 : 4
I not understand. Can you show me in model form. Thanks..

Thanks alot
