On Monday, There were 18 cows and 12 horses in a field. On Tuesday, there were 4 more horses in the field. Write a ratio to show the relationship between the number of horses and the total number of animals in the field on Tuesday.
A 16/30
B 8/17
C 12/34
D 18/34
On Monday, there were a total of 18 cows + 12 horses = <<18+12=30>>30 animals in the field.
On Tuesday, there were a total of 18 cows + 12 horses + 4 horses = <<18+12+4=34>>34 animals in the field.
The ratio of horses to the total number of animals on Tuesday is 12 horses / 34 animals.
Therefore, the correct ratio is C) 12/34.
