ANS: B b


Feedback: Add the amount of ounces consumed. First, change any mixed number to a fraction by
b b b b b b b b b b b b b b b


multiplying the whole number by the denominator and then adding that total to the numerator. For the
b b b b b b b b b b b b b b b b b


coffee, 4  2 = 8 + 1 = 9/4; for the beef broth, 2  1

= 2 + 1 = 3/2. Then add: 9/4 + 2/3 (ice cream) + 3/2. When fractions have different denominators, find

the least common denominator (LCD). For 2, 3, and 4, the LCD =

12. Rewrite each fraction using the LCD; divide the LCD by the denominator of each fraction and then

multiply that result by the numerator of the fraction. The new fractions to be added are 27/12 (coffee),

8/12 (ice cream), and 18/12 (beef broth). After conversion of the fractions, the numerators are added
