The amount of water each hiker drank is 1/6 gallon
Total gallon of water shared = 1/2
Number of people between which sharing occurs = 3
Since the sharing is done equally ;
The area mode wo use will be :
a + a + a = 1/2
Where, a is the amount drank by each person :
a + a + a = 1/2
3a = 1/2
a = 1/2 ÷ 3
Take the reciprocal of 3 and change the sign to ×
a = 1/2 × 1/3
a = 1/6
Hence, each hiker drank 1/6 gallon
