Sorry dear parents, need solution for the question below.


Draw diagrams / Guess and Check.

There are 8 goats and ducks altogether.
Some had 2 legs and some had 4 legs.
The animals have 20 legs in all.
How many goats are there?

Thanks.

P/s: The sch teacher said to get as less as possible for the number of goats.

DK did mention she had returned him the gifts from Prof Tey when she went to his office to collect the payment from him. Most of the gifts were books.

What payment? I thought she denied any payment? :scratchhead:[/quote]The $1,278.60 payment for a dinner Prof Tey hosted. When she came back from USA, she went up to Prof Tey's office with one of her male friend to collect this payment. Tey gave her cash of $1000 in an envelope.

Dear parents,

Is the answer for question 18 must be answer 2? Can it be answer 1 or not? I think answer 1 can be accepted too, am I right? :nailbite: What do you think?

Please advice. (as the teacher is waiting student's parent to verify the marks before submitting to record in report book.)

Thanks !!

DD forgot to put her dirty clothing immediately to washing machine again. I was mad! :mad:


I said,\"Pull your ears 20 times now!\"
DD,\"No.... mummy, please... I don't want to pull ears...\" (requested with red eyes)
Me, \"No! You want to pull 20 times or 200 times? Choose.\"
DD,\"20 times.\" She started to pull her ears silently.

............ 2 weeks later......

DD,\"Mum, if I do my Math worksheets (5 pages) all correctly, can you give me $1?\"
Me,\"Why should I give you money? This is your job. You should do it without any conditions!\" :roll:
DD,\"Yes! You must give me money. You want to give $1 or $10? Choose!\" (with smiling face)
Me,\"What?!\" :faint:

Oh yes... Thank you!!
