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

A) 2/5
B) 3/5 .
C) 2/25

eate a fraction by dividing 10 oz (remaining portion) by 25 oz (total
1l 1l 1l 1l 1l 1l 1l 1l 1l 1l 1l 1l
portion). Therefore, 10 divided by 25 = 10/25. To reduce fractions, find the largest

2. A patient/client was prescribed 240 mL of Ensure by mouth and a supplement b
1l 1l 1l 1l 1l 1l 1l 1l 1l 1l 1l 1l 1l
ut consumed only 100 mL. What portion of the Ensure remained?

Ensure that remains, create a fraction by dividing 140 mL (remaining portion) by 240
1l 1l 1l 1l 1l 1l 1l 1l 1l 1l 1l 1l 1l
.
mL (total portion). Therefore, 140 divided by 240 = 7/12. To reduce fractions, find the
1l 1l 1l 1l 1l 1l 1l 1l 1l 1l 1l 1l 1l 1l
largest number that can be divided evenly into the numerator and the denominator
1l 1l 1l 1l 1l 1l 1l 1l 1l 1l 1l 1l
(20); 140 divided by 20 (140/20) = 7; 240/20 = 12. The fraction r
1l 1l 1l 1l 1l 1l 1l 1l 1l 1l 1l 1l 1l 140/240 can be 1l 1l
educed to its lowest terms of 7/12.
