Salam

The  things  to be discussed are:

Ratio

Rate

Proportion.

2)  when do they teach  division
Example  12 divided by  3

3)  see thepicture below


    X!   1!   2!

     Y!  2 !   4!

Here   1 : 2  =  2: 4

Different quantities become rate.

So about average?

it looks simple  but ...how do you teach?

how about probability

how about a tree diagram.  Is it a product of multiplication?

tq.

think plz
