each box of 4 has 1 more apple than each box of 3. there are 5 more boxes of 3. 5 x 3 ＝ 15 15/1 ＝ 15 Hence there will be 15 boxes of 4. 15 x 4 ＝ 60 Hence there will be 60 apples.

Tks!I will try to digest it!

welcome 😊 u understand why 15/1 ?

Hehe....that the part that I don't understand that why need to slowly digest it.

total number of apples does not change. if i put 4 apples into 1 unit of box, i would have 1 unit with 5 extra boxes if i put 3 apples into each box. agree?

the 5 extra box contains 15 apples. the reason why i only need 1 unit of box if i put 4 apples into each box, is because the 15 "extra" apples can be placed into the 1 unit of boxes nicely.

Agree that the number of apples does not change.But cant visualise.think it is my command of english.will get my hubby to see if he can explain it to me thru your explanation.

Yueh Mei with the model drawing I can understand better now.but what about the part that Shu Hao did 15/1?must we show this part in the working?

It's 15/1 because you're distributing 1 apple to each box. Can just show the step although the calculation is trivial.

Oic!tks Yueh Mei and Zhong Shu Hao!

haha paiseh Karen Goh im in sch when commenting 😝

No worry Zhong Shu Hao!appreciate ur immediate response!

Thank you for your time, shu hao. No need to pai seh.

My boy tried it via trial and error, using multiples of 3 and 4. He said he's got 60 apples. But I like Zhong Shu Hao's short and sweet method. :)

Tks Elaine Eo think I did not really understand the Q at first.!

Hope this model helps. Ans 280

Yes. It does. Thank you very much.

Adrian Ng...thank you so much. Really appreciate it. 😊

340g. . She forgt to write grams..

LOL

😡😡..I kept thinking what's wrong. ..its sould be 340. .

Now I know " G".....

No offence meant... D:

Especially in Section B, (open ended structured Q), you MUST check that you have written your units. Can u imagine losing 1 mark for every units missing?! Thats more 5 priceless marks gone!!

Yes..totally agreed 👍👍

Thank you so much Yeo See Yeong. 😊
