Mathematics

wuwu~~

i cant type chinese...dont know why...

 

never mind,

to show that i am a bi-lingua speaker

i'll use english this time

 

well...as usual (every Tuesday evening)

i went to the MCYC (Methodist Child and Youth Centre) to be their volunteer

conducting a one-to-one tuition for the primary or secondary kids

hehe...i am a tutor now, teaching a primary 5 girl

 

HA!

she is pretty good in maths i think

she is from china

so

can i conclude that everyone from china are superb in maths?

i really think that a chinese is always very good in maths, esp those from china

 

well...today i encountered a math question

not difficult actually..but i think it is super hard for a primary 5 student

because we need to use algebra method to solve the question

here is a sample of the questions:

 

"Lily scored an average of 81 marks for her English, Chinese, Science and Mathematics.

She scored 1/4 less marks for chinese than english,

2/3 more marks for science than chinese and

4 more marks for maths than english.

How many marks Lily did score for her English?"

 

hehe...

come on friends

take out a pen and a paper and start scrabbling

use any method you like to solve this question...

DONT SCROLL DOWN YET

TRY DOING IT FIRST!!
