Question

Cars Benito wants to buy a car. He is considering two different models.Model A is 7 1/8 ft wide. Model B is 93 in. wide. Part a. express the width of each car in ft using a decimal. Part b. which car is wider?

Answer 1

Model A is 7.125 ft wide. Model B is 93/12 = 7
`(9)/(12)` or 7
`(3)/(4)` which can be written as the decimal 7.75

To compare we add a zero to make them the same length

7.125 < 7.750 so Model B is wider by .625ft (or 5/8 of a foot)

Answer 2

a). Model A = 7.125 ft

Model B = 7.75 ft

b). Car B is wider than Car A.

Explanation:

a). Model A of the car is
`7(1)/(8)` ft wide.

Model B is 93 inches wide.

Since 12 inches = 1 foot

So, 1 inch =
`(1)/(12)` foot

Therefore, 93 inches =
`(93)/(12)` feet

=
`(31)/(4)` feet or
`7(3)/(4)` feet

Length of the model A =
`7(1)/(8)` ft = 7.125 ft

Length of the model B =
`7(3)/(4)` ft = 7.75 ft

b). Now we have to compare both the models having measures
`7(1)/(8)` ft and
`7(3)/(4)` feet respectively.

As we ave seen in part (a), model B is more wider than model B.

Therefore, car B will be more wider.
