Final answer:
The actual number of surfers and swimmers at the beach can vary. There are infinite possible numbers that satisfy the given ratio of 6:16.
Step-by-step explanation:
To find the actual number of surfers and swimmers at the beach, we can set up a proportion using the given ratio:
Surfers : Swimmers = 6 : 16
Let's assume the actual number of surfers is 6x and the actual number of swimmers is 16x, where x is a positive constant.
So, we have:
6x : 16x = 6 : 16
Now, we can cross-multiply to solve for x:
6x * 16 = 6 * 16x
96x = 96x
Since the equation is true for all values of x, there are infinite possible actual numbers of surfers and swimmers at the beach.
