Answer explanation

It is given that for 5 unit ratio represents 15 animals.

Therefore, 1 unit ratio = 15 : 5 = 3 animals

Then the number of ducks:

7 unit ratio = 7 x 3 = 21 animals

So there are 21 ducks in the farm

Dana, Budi and Maria has toys in the ration of 2 : 3 : 7. if Budi has 12 toys, find the total number of toys they have.
