Hi. See image for details. :)

thanks a lot for ur clear exp.

This is done by my Daughter. She is a p6 girl from Woodlands Ring Primary School.

can u pls explain how it became 10 units

Before: Jay has 2 times as many as Ryan. So, Jay has 2 units, Ryan has 1 unit. Total units is 3. After: Jay has 2/3 of Ryan. So, Jay has 2 units, Ryan has 3 units. Total units is 5. Their total marbles remains the same throughout. So, how can total units change from 3 to 5? The answer: Make the total number of units to be 15 for 'before' and 'after'. 15, because it is a common multiple of 3 and 5 for the total units. Hence, in the 'before' diagram, Jay will have 5 x 2 = 10 units. :)

Thanks

Sorry answer David shld be 23 .. typo error

Thanks Raymond .. can be very challenging pri 3 question

A+B+D->51 A+D->34 B+D->40 ---------------------- A+B+D+D->74 51+D->74 D->74-51= 23(ans)

(A+D)+(B+D)-(A+B+D) =34+40-51 =23

Oops! Thanx all. I minus salah. Should be 23 not 33. Careless. But my working correct. Please give me one out of 2 marks

Ani+Davi=34 51-34=17 Bala+Davi=40 51-40=11 Ani+Bala =17+11=28 51-28=23. David=23.

I beg to differ. I would tend to think it all boils down to question exposure ☺

Firdaus...for PR 3...can draw step by step model....

Complicated Maths made easy. From Dr. Andy Lim 😊😉

Hi, Candy Chan. If 20% of the beans are red, 80% of the beans are green. Hint 1: Calculate the mass of the green beans. (0.8 x 2105kg = :) ) This mass, if you observe, has no change to it throughout the problem. So, if :) represents 70% now, what is 100% mass? Once you get this 100% mass, take the difference with 2105kg. You will then know the mass of red beans were bought. Try this hint out and let me know.

Hint 1 : 1684kg, but the number is very big .

You are right! It is 1684 kg. You got the mass of the green beans!

So, 421kg is the mass of red beans?

Yes...but you don't calculate it now. It will confuse you.

New mass of beans - 2105kg of beans = additional mass of red beans bought.

Hi, Aini Rizal. Here is the solution. :) What difficulty did you have with the problem?
