Answer:
Gary was more thirsty.
Explanation:
Given that On a hot summer day, John drank 5⁄11 of a quart of iced tea; Gary drank 7⁄10 of a quart; and Carter drank 3⁄5 of a quart.
We have to tell which man was the most thirsty.
The man which drank more iced tea was most thirsty
John drank=
=0.4545 of quart
Gary drank =
=0.7 of quart
Carter drank =
=0.6 of quart
From above 3 we say that Gary drank more water than other 2. Therefore, Gary was more thirsty.
