lianna [129]

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:

\frac{m}{24}  = \frac{8}{3}  \implies m = \frac{8}{3} \times 24 = 64

⇒  m = 64

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