A) 2/5
B) 3/5
C) 2/25
D) 25/25
Ans: A
Feedback: Subtract the quantity of water the client drank (15 oz) from the total available q

uantity (25 oz): 10 oz remain. To determine the portion of the water thatremains, create a
! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
fraction by dividing 10 oz (remaining portion) by 25 oz (total portion). Therefore, 10 divide

d by 25 = 10/25. To reduce fractions, find the largest number that can be divided evenly int

o the numerator and the denominator (5). Tendivided by 5 (10/5) = 2; 25/5 = 5. The fracti

on 10/25 can be reduced to its lowest terms of 2/5.
