Answer:
The number of fishing boats in the bay = 64.
Step-by-step explanation:
The total number of sailboats = 24
Let us assume the number if fishing boats in the bay = m
⇒ Ratio of fishing boats to sailboats in a bay = m : 24.
Now, the ratio of fishing boats to sailboats in a bay is 8 : 3.
So, by the RATIO OF PROPORTION:

⇒ m = 64
Hence the number of fishing boats in the bay = 64.
