Answer:
15 pigs
Explanation:
Let the number of cows be 7x
∴ The number of pigs = 5x
Therefore number of cows = 7x = 21 cows
=> x = 21/7
=> x = 3
∴ Number of pigs = 5 * 3 = 15
Hence the number of pigs in the farm is 15

Ratio of cows to pigs at a farm is 7 to 5.
If there are 21 cows in the farm,
(so coefficient is 3 )
to calculate pigs multiply 5 by 3
[tex]=5*3\\=15[/tex]
Therefore, number of pigs in the farm is 15.
