Ratio problems

Download the lesson here.

Just a load of interesting (ish) ratio problems to work though.

I used bar modelling. I am increasingly into bar modelling for KS3, although I’m still not massively convinced when it comes to negatives.

I call these ‘reverse’ ratio problems. I don’t know if that’s the correct terminology.

I have been watching a lot of Queer Eye recently.

I like bar modelling for questions like this.


Some questions adapted from Don Steward and White Rose Maths Hub’s Barvember 2017.

No posts for two weeks now. I’m on holiday. When I get back, Pythagoras and Trig!
