For P3, it is tough. Do they learn decimal in P3?

1-4/12-2/6=12/12-4/12-4/12=4/12

4/12 * 1000 ml = 333.333ml = 0.333 litre

Is this anwer correct?

My goodness. The kids should think on the spot to answer all these questions. I am sure my DD will not know that she can write 4/12 or 1/3 litre and she will think think think forever.

I was also confused as in how to convert to litre? Currently asking DD to check with teacher to see if there is a typo error in that question. Will update again.

Mrs Ng went shopping. If she bought a dress , she’d be short of $4.50. If she bought a skirt,she’d be left with $11.70. How much more expensive was the dress then the skirt.

Hi SPI,

Hope the model is clear.

sorry I realise that the amount should be $11.70 not $11.50.
Please change that. So the answer will be $16.20

From Ai Tong Pri 3 SA1 Maths:


A teacher gave her students some balloons. If she gave 6 balloons to each student, she will have 2 balloons left. If she gave 8 balloons to each student, she will be short of 2 balloons. What is the smallest possible number of students she has?

I'll probably use trial and error method and hope that she is not giving out >100 balloons.
Ans: 2 students...correct?

2+2/8-6
= 4/2
=2

She had 2 students.
