Craig bought a 3-foot-long baguette and then made 4 equally sized sandwiches with it.
a. what portion of the baguette was used for each sandwich? draw a visual model to you solve this problem.
b. how long, in feet, is one of craig’s sandwiches?
c. how many inches long is one of craig’s sandwiches?

Part a) For each sandwich was used 1/4 of the baguette

Part b) One of Craig’s sandwiches is 3/4 ft long

Part c) One of Craig’s sandwiches is 9 in long

Step-by-step explanation:  

Part a) What portion of the baguette was used for each sandwich?

we know that

The baguette is divided in 4 equally sized sandwiches

The baguette represent the 100%

so

Each sandwich represent

Convert to fraction number

therefore

For each sandwich was used 1/4 of the baguette

see the attached model to better understand the problem

Part b) How long, in feet, is one of Craig’s sandwiches?

we know that

Divide the total length of the baguette by the number of sandwiches

The total length of the baguette is 3 ft

The number of sandwiches is 4

so

therefore

One of Craig’s sandwiches is 3/4 ft long

Part c) How many inches long is one of Craig’s sandwiches?

we know that

Convert ft to in

To convert feet to inches multiply by 12

therefore

One of Craig’s sandwiches is 9 in long

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21
