Aurelia went to the doctor’s office. The nurse measured her height as 44 inches. If Aurelia needs to be 4 1/2 feet to ride an amusement park ride, how many more inches must she grow?

Solution:

Step 1: Convert the mixed number to an improper fraction:


4(1)/(2)\text{ f}eet=(9)/(2)\text{ f}eet\text{ = }4.5\text{ f}eet.

thus, if Aurelia needs to be 4 1/2 feet to ride an amusement park ride, this is equivalent to saying that Aurelia needs to be 4.5 feet to ride an amusement park ride.

Step 2: Convert the above obtained to inches:


4.5\text{ f}eet(\frac{12\text{ inches}}{1\text{ f}eet})=54\text{ inches}

Step 3: Calculate the difference between Aurelia's height and the value obtained in the previous section:


54\text{ inches - 44 inches = 10 inches.}

So that, we can conclude that the correct answer is:

10 inches.
