Lets get started :)

1) 1 dozen of eggs costs 3 cowry shells
6 dozens of eggs cost ? cowry shells

We can put this into ratio form and solve my cross multiplying

(dozen)/(cowry.shells)


(1)/(3) = (6)/(?)
18 = ?

6 dozen of eggs is worth of 18 cowry shells
Your answer is C) 18 cowry shells

2) I have 7 cowry shells, 1 dozen costs 3 cowry shells
We can only purchase 2 dozens of eggs

2 x 3 = 6 cowry shells, we do not have enough cowry shells to buy more
Your answer is option B) 2 dozens
