(25 oz): 10 oz remain. To determine the portion of the water that remains, create a fraction by
p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3
dividing 10 oz (remaining portion) by 25 oz (total portion). Therefore, 10 divided by 25 = 10/25.

Feedback: Subtract the quantity of Ensure the client consumed (100 mL) from the total available
p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3
quantity (240 mL): 140 mL remain. To determine the portion of the Ensure that remains, create a
p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3
fraction by dividing 140 mL (remaining portion) by 240 mL (total portion). Therefore, 140 divided
p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3
by 240 = 7/12. To reduce fractions, find the largest number that can be divided evenly into the
p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3
numerator and the denominator (20); 140 divided by 20 (140/20) = 7; 240/20 = 12. The fraction
p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3
140/240 can be reduced to its lowest terms of 7/12.

Feedback: Add the amount of ounces consumed. First, change any mixed number to a fraction by
p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3
multiplying the whole number by the denominator and then adding that total to the numerator. For
p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3
the coffee, 4 2 = 8 + 1 = 9/4; for the beef broth, 2 1
p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3
= 2 + 1 = 3/2. Then add: 9/4 + 2/3 (ice cream) + 3/2. When fractions have different denominators,
p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3
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
p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3
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
p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3 p3
are added together and the fraction is reduced to the lowest terms.
