Question

Max us 5 3/4 ft tall. Felisa is 4 11/12 ft tall. How much taller is max than felisa?

Answer 1

The first thing you want to do is convert both of these mixed fractions into improper fractions. For instance, since you have that Max's height is 5 and 3/4 feet, you want to convert 5 feet into 20/4 feet and add that to the remaining 3/4 feet to get an improper fraction of 23/4 feet. This makes it easier to manage later.

Next, you want to make sure the denominators of both Max's height and Felisa's height are the same, since ultimately you want to subtract Felisa's height from Max's height and find their change in height. Since Max's height has 4 as a denominator and Felisa's height has 12 as a denominator, you want to multiply Max's ENTIRE height by 3 in order to convert it into a numerical value over 12 for his height.

Once you have that, simply subtract her height from his to find the answer: the change in height between Felisa and Max.
