Answer:
12 people can walk 24 dogs. 
Explanation:
Given information,
→ 6 people can walk 12 dogs. 
→ People required for 24 dogs = ? 
Let us assume that,
→ Missing value = p 
Forming the equation,
→ 6/12 = p/24 
Then the value of p will be,
→ 6/12 = p/24 
→ p/24 = 6/12 
→ p × 12 = 6 × 24 
→ 12p = 144 
→ p = 144/12 
→ [ p = 12 ] 
Hence, the value of p is 12.
