Dat model should be enuf.....

Thanks Zhong Shu Hao. She got the model correct but don't know how to progress beyond.

When going through, Jackie + Linda = 450 1 unit + Linda = 450 (shade the portion of Jakie) 1 unit + 1 unit + 250 = 450 (shade the potion of 1 unit and 250 separatrly)

then find 1 unit

1u=100?

correct

for children, maybe using different coloured pens will help more.

Children luv colours.... haha

I agree and thank you so much

Welcome!

My P2 daughter working: 450-250=200 200/2 = 100

Thanks Yvonne Quah Su-Sim much clearer:-)

Read with reference to this.

Do you know what is an exterior angle?

The sum of the exterior angles is 360°.Since this is a regular polygon number of sides is 360 degree/ 24 degree = 15 . Number of sides is 15.

Thanks
