it seems like you have the answer already. but heres how its calculated.

(100)/(15) = (?)/(3)
so the missing number is 20 **cross multiply 100 and 3 to get 300 then divide 15 into 300 to get 20**


(160)/(100) = (80)/(?)
so the missing number is 50
**cross multiply 100 and 80 to get 8000 then divide 160 into 8000 to get 50**
