Answer:
3
Step-by-step explanation:
The ratio of adult dog to puppies is 3:2
There were 12 puppies that day
Number of adult puppies can be calculated as follows
= 3/2× 12
= 3 ×6
= 18
There were 15 adult dogs in the park on Tuesday
Hence the difference can be calculated as follows
= 18-15
= 3
The missing justification is the Subtraction property of equality.
This is because to get 1/3x=4, you need to subtract 3 from both sides.
