Question

Please help the below question:-

Mr Tong rears duck and cows on his farm. The ratio of the total number of legs of the ducks to the number of legs of the cows is 4:7. Find the minimum number of ducks Mr Tong has in his farm. 

Thank you!

Answer

   Ducks Legs              Cows Legs

                4                         7

 

Since cows have 4 legs, minimum number of cows legs divisible by 4 is  28 ( as a multiple of 7, x4)

So, minimum duck legs = 4 x 4 = 16

Hence minimum number of ducks = 16/2 = 8
