1. A patient/client was instructed to drink 25 oz of water within 2 hours but was
only able to drink 15 oz. What portion of the water remained?
A) 2/5

t n of the water that
remains, create a fraction by dividing 10 oz (remaining portion) by 25 oz (total
portion). Therefore, 10 divided by 25 = 10/25. To reduce fractions, find the largest

number that can be divided evenly into the numerator and the denominator (5). Ten
divided by 5 (10/5) = 2; 25/5 = 5. The fraction 10/25 can be reduced to its lowest
terms of 2/5. .

largest number that can be divided evenly into the numerator and the denominator
(20); 140 divided by 20 (140/20) = 7; 240/20 = 12. The fraction 140/240 can be
reduced to its lowest terms of 7/12.

Ans: B
Feedback: Add the amount of ounces consumed. First, change any mixed number to
a fraction by multiplying the whole number by the denomitation and then adding that
total to the numerator. For the 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 o f the fraction. The new

fractions to be added are 27/12 (coffee), 8/12 (ice cream), and 18/12 (beef broth).

A) 360
B) 420
.
C) 510
D) 600
Ans: B .
Feedback: The coffee cup holds 180 mL. The client drank 2⅓ cups. To estimate the
total number of milliliters consumed, multiply 180 7/3 (2⅓). When a mixed number
.
is present, change it to an improper fraction by multiplying the whole number by the
denominator and then adding that total to the numerator: 2 3 = 6 + 1 = 7/3.
Therefore, 180 mL × 7/3 = 420 mL (180 ÷ 3 = 60 × 7 = 420).
