Question

14. In science class, students are growing plants. The table shows the change in the heights between the heights of some students' plants and the height of last year's tallest plant. Order the changes from least to greatest. Student Ellen Juan Patty Sonny Change -2-2/4 in. 1 ft 3.1 in. 75 ft​

Answer 1

To order the changes in height from least to greatest, let's convert all the measurements to the same unit, such as inches. Then we can compare the values.

The given changes are as follows:

Ellen: -2 2/4 in. (or -2.5 in.)
Juan: 1 ft 3.1 in. (We need to convert this to inches)
Patty: 75 ft (We need to convert this to inches)
Sonny: 75 ft (We need to convert this to inches)

To convert Juan and Patty's measurements to inches, we multiply the number of feet by 12 (since 1 foot is equal to 12 inches) and add the inches.

Juan: 1 ft * 12 in/ft + 3.1 in. = 12 in. + 3.1 in. = 15.1 in.
Patty: 75 ft * 12 in/ft = 900 in.
Sonny: 75 ft * 12 in/ft = 900 in.

Now, we have the following changes:

Ellen: -2.5 in.
Juan: 15.1 in.
Patty: 900 in.
Sonny: 900 in.

Ordering these changes from least to greatest:

-2.5 in. < 15.1 in. < 900 in. < 900 in.

Therefore, the changes in height from least to greatest are as follows:
Ellen: -2 2/4 in.
Juan: 1 ft 3.1 in.
Sonny: 75 ft
Patty: 75 ft
