Carter made a model of a boat. The length of the actual boat is 45 feet. Carter’s model has a length of 7 1/2 inches. What scale did Carter use to build his model?

A)1 in. = 4 ft
B)1 in. = 5 ft
C)1 in. = 6 ft
D)1 in. = 7 ft
E)1 in. = 8 ft

Option C)1 in. = 6 ft

Step-by-step explanation:

Up to know we have the following equality:

45 f = 7 1/2 in

Or what is the same that:

45 f = 7.5 in

If we divide both sides of the equation by 7.5 we will get the equivalence to 1 inch:

45/7.5 f = 7.5/7.5 in

6 = 1 in

So, the correct answer if option C)1 in. = 6 ft

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.
