Martha is covering kitchen shelves with shelving paper. She has 6 shelves that are each 1 ¾ feet long. She buys 13 ¼ feet of shelving paper of the correct width. Which equation can be used to determine how much paper she will have left over?
would that equation be 6(1 3/4ft.)= 13 3/4ft? If not explain how I should work it out.
Thank you.
13 1/4 - 6(1 3/4) = S

The chocies are:
6(1 3/4) = S
13 1/4 + 1 3/4 - 6 = S
13 1/4 - 6(1 3/4) = S
13 1/4(6) + 1 3/4 = S
6(1 3/4) - 13 1/4 = S

This was the answer.
C)13 1/4 − 6(1 3/4) = S
No.
What are your other choices?
To determine how much paper Martha will have left over, we need to subtract the total length of the shelves from the total length of the shelving paper she bought.
First, we need to convert the measurements to the same unit. Martha's shelves are each 1 ¾ feet long, and she bought 13 ¼ feet of shelving paper. Let's convert 1 ¾ feet to a fraction with the same denominator as 13 ¼ feet.
1 ¾ feet can be written as 7/4 feet.
Now, we can calculate the total length of the shelves by multiplying the length of each shelf by the number of shelves. In this case, there are 6 shelves, so the total length of the shelves is:
6 * (7/4) = 42/4 = 10 ½ feet.
Now, we can subtract the total length of the shelves from the total length of the shelving paper Martha bought:
13 ¼ feet - 10 ½ feet.
The result is 2 ¾ feet.
Therefore, the correct equation to determine how much paper Martha will have left over is:
13 ¼ feet - 10 ½ feet = 2 ¾ feet.
