Ratios Notes and Videos
Ratios Notes 8 - finding the missing quantity (look only at the cross multiplication method – the one we did in class)
Ratios Video 5 - Dividing quantities in a given ratio
(in this video the teacher first divides then multiply. In class when we multiplied by a fraction we were doing the same thing so you are free to choose which method you prefer :) )
