Kallie drank 12.75 gallons of water in 3 weeks. She drank the same amount of water each day. Estimate how many gallons she drank in one day.

607 miltliters per day

Step-by-step explanation:

Step one:

given data

Kallie drank 12.75 gallons of water in 3 weeks

if she drank the same amount each day, then in one day she will drink

Notethere are 31 days in 3 weeks (7 days make 1 week)

Step two:

Hence in one day she will drink

= total volume of water/number of days

= 12.75/21

=0.607liters per day

or

607 militliters per day

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9
