Thanks Helen,actually I were more to looking for drawing model because anyhow I could not understand the model in green pen in the photo,your method enlightened me.The model is wrong,again thanks

So sorry,wrong spelling Raymond,大人有大量

Most welcome. 😊

This is a P5 question,can anyone help?My girls got it correct but she could not explain to me,where are the number 8 and 9 come from?

9 is the area of small square, 8 is the # of small squares on each side of the biggest square

8x8 is the total # of the small squares in the biggest square

I replicate the original diagram below the original figure to better view of the question

Sorry i still don ustd

let me try again

This is wonderful !thanks a lot Mr Ong

Glad you find it useful. Like all problem solving, focus on the info and expand from there

Thanks for the trouble. Sorry i m actually a little slow. I don know why we use 8

I mean how do u divide them? What if the question is changed to the smallest area of square is 16cm square?

How many small squares are there on each side of the biggest square?

At least make the effort to zoom in the question for us lah..

1/3 are girls, so how many are boys?

and in Math, the word "of" often means multiply

so 1/3 of the people who can swim means that 1/3 x People who can swim

If 1/3 of the swimmers are girls, then the other 2/3 of the swimmers are boys. Since the swimmers are 5/6 of the class, the boy swimmers are 2/3 of 5/6. Since "of" means to multiply in math, 2/3 x 5/6= 5/9. 5/9 of the class are boy swimmers.

Thank you 👍

130% = 3900 1% = 3900/130 = 30 30% = 900 45% of Alina and Brenda combined = 900 1% of Alina and Brenda combined = 900/45 = 20 100$ of Alina and Brenda combined = 2,000 Alina has thrice as much money as Brenda. So Alina has $1,500 and Brenda has $500.

How to draw the model for this question ??

First part

Second part

Candy Chan From Robert Yeo explanation... $2000 is 100% of Alina and Brenda Money.. Alina->3u Brenda- >1u 4u-> $2000 3u-> $2000÷4 x 3= $1500 I find drawing models for this QN quite confusing and time consuming... Use Robert's method-> working from Mother's Money of 30% increased in savings.. My method is just showing how to work from the front(Alina&Brenda's Money)..just an alternative solution... Robert explanation is the best way to solve...-> try to move away from models drawing if possible...
