Hi Candy08, you may consider my dd1 ex tutor Miss Goh. She happens to be a home tutor in the West as well. She is a very experienced tutor who knows her stuff well and my dd1 was very motivated to study when under guidance and did consistently well. If you are keen, you may contact hef at 93989072. All the best!

0.034 rounded off to the nearest 0.01 is 0.03
0.025 rounded off to the nearest 0.01 is also 0.03

So anything between 0.025 and 0.034 rounded off to the nearest 0.01 is 0.03.

Hope that helps. 📏😊
Sorry, unfortunately, your answer is wrong. I am a math teacher and am aware of the confusion this question causes to people not familiar with bounds.

The cambridge solution to a similar question in the o level is same as mine. Unfortunately, only teachers have access to the report.
Thank you for your reply. Actually I was just stating the general idea for rounding off a number but not answering the question per se because i am aware that this question might cause confusion. Thank you for the insight! :smile:

No Problem.. this is one of the question that causes students to falter...
another question in the O level that confuses many is "provide your answer to a reasonable accuracy".... students often fail to understand the mathematical significance of that question beyond practical aspects...

From my boy. Btw he mentioned that this was more MO than normal Math. Is he correct or does normal Math nowadays encompass elements of MO too?

b): there is a trap here. the correct answer is 1+(6/n) or (n+6)/n

a) 19/16
b) (n+6)/n
c) no, as 200 is not a power of 2
