Thanks MathsGuru,


The qn really has a pen. I was puzzled too. Anyway, my girl will check with her teacher to see if there is a typo error. Once again, thank you for your help.

Mr Sachiko,


I think Tang has already solved this question on 9 April and the answer is 3 markers. You may want to take a look at the workings.


Good night.

Workings by Tang

1 - 2/5 = 3/5

1/3 x 3/5 = 1/5

3/5 - 1/5 = 2/5

2 u --> $0.90 --- This is the amount spent on markers

1 highlighter --> $0.90

1 marker --> 1/3 x 0.90 = $0.30

0.90/0.30 = 3 markers

He bought 3 markers.

Hi MathsGuru


Good morning.

Ali, Bala and Charles shared a tin of cookies. Ali took 5/6 of the tin of cookies and 1/3 of a cookie. Bala took 5/6 of the remaining tin of cookies and 1/3 of a cookie. Charles received only 2 cookies. How many more cookies did Ali have than Bala?

Thanks.

[Guan Hui]

After Ali took the cookies.

Bala 5/6 of the remaining cookies and 1/3cookie and charles received the rest(2 cookie)

1-5/6=1/6 of the remaining cookie
(2+1/3) cookie = 1/6 of the remaining cookie
so the total amount of remaining cookie= (2 +1/3) x 6
= 14 cookies
No. of cookie Bala received= 14-2 =12 cookies

From the beginning
Ali 5/6 of total cookies and 1/3cookie
(14+1/3) cookie = 1/6 of total cookies
So the total amount of cookie= (14+1/3) x 6
= 86 cookies
No. of cookies Ali received= 86-14=72 cookies

How many cookies more? 72-12=60 cookies
