Respuesta :

so, there are 48 states, let's divide them into 16 groups  (because 7+9=16)


48/16=3

so that means there are 16 groups of 3 states.

and those groups are in a ratio of 7:9, seven to 9 groups.

I assume that the 7 refers to the states that border an ocean, then the number of states will be 7*3=21

Answer:  21 states

Step-by-step explanation:

Since, The total number of states in the continental United States is 48 in which some are in the border of ocean and some are not in the border of ocean.

According to the question,

The ratio of the states having the border to the ocean and not having the border to the the ocean = 7 : 9

Let the states having the border to the ocean = 7x

The the states do not having the border to the ocean = 9x

Thus,  7x + 9x = 48

⇒ 16 x = 48

⇒ x = 3

Thus, the states having the border to the ocean = 7 × 3 = 21
