1. A hpatient/client hwas hinstructed hto hdrink h25 hoz hof hwater hwithin h2 hhours
hbut hwashonly hable hto hdrink h15 hoz. hWhat hportion hof hthe hwater hremained?

A) 2/5
B) 3/5
C) 2/25
D) 25/25
Ans: A
Feedback: hSubtract hthe hquantity hof hwater hthe hclient hdrank h(15 hoz) hfrom hthe
htotal havailable hquantity h(25 hoz): h10 hoz hremain. hTo hdetermine hthe hportion hof

hthe hwater hthathremains, hcreate ha hfraction hby hdividing h10 hoz h(remaining

hportion) hby h25 hoz h(total hportion). hTherefore, h10 hdivided hby h25 h= h10/25. hTo

hreduce hfractions, hfind hthe hlargest hnumber hthat hcan hbe hdivided hevenly hinto

hthe hnumerator hand hthe hdenominator h(5). hTenhdivided hby h5 h(10/5) h= h2; h25/5

h= h5. hThe hfraction h10/25 hcan hbe hreduced hto hits hlowest hterms hof h2/5.

Ans: B
Feedback: hSubtract hthe hquantity hof hEnsure hthe hclient hconsumed h(100 hmL)
hfrom hthe htotal havailable hquantity h(240 hmL): h140 hmL hremain. hTo hdetermine

hthe hportion hof hthe hEnsure hthat hremains, hcreate ha hfraction hby hdividing h140 hmL

h(remaining hportion) hby h240hmL h(total hportion). hTherefore, h140 hdivided hby h240 h=

h7/12. hTo hreduce hfractions, hfind hthehlargest hnumber hthat hcan hbe hdivided hevenly

hinto hthe hnumerator hand hthe hdenominator h(20); h140 hdivided hby h20 h(140/20)
