Q&A - P2 Math

[Taurus]

Anyone can confirm answer is 76 and not 67 as in answer sheet :

Qns : i am a two digit number. The difference between my tens digit and ones digit is 1. My digits add up to 13. What number am I?

Hi Tauras,


The answer could be both 76 and 67.

Since the question states: the difference between my tens digit and ones digit is 1, it does not matter in which place the \"7\" is.

If the question mentioned, \"When we subtract the number in ones digit from the number in tens digit, the answer is 1\" --> then the answer will definitely be 76.

just my opinion on this..

Hi

Could anyone help to solve this? Thanks.
Find the missing number
16 - 8 - 12 - 6 - 10 - ? - 9

Is the answer 5?

divide by 2, then add 4.

16/2 = 8
8+4 = 12
12/2 = 6
6 + 4 = 10
10/2 =5
5 + 4 = 9

Hi Chamonix,
I do not know the answer and had sent email to check with the teacher.
No reply from her yet.
My answer is the same as you.
Thanks for your reply.

Hi Big Devil,


You may like to draw or use pictoral aids to show your child.

Thanks, teachingmum! Will give that a try.

I suppose this will work for the popular \"total number of legs is X, how many pigs and how many chicken?\" kind of questions too right?

Hi Chamonix,

Just received a call from the teacher. Answer is 5.

ksi:

a) R
b) O, S, U
c) D, R

Trick question? (a) and (c) is similar question.

Same answer as my DD, also the answer given by the assessment book.
But DD's teacher gave the answer as
a) R, U
b) O, S
c) D, R, U

WCW:

a) G, J, U
b) C, O, S
c) B, D, P, R
Assuming using Caps...

Sorry, WCW. Should have made myself clear that we are looking at the letters that formed the word DINOSAUR.

But interestingly, you also gave \"U\" as one of the answers for (a).

So why isn't \"U\" one continuous curved line?
