Answer: The quantity of the water received by each student = 3.75 liters.
Step-by-step explanation:
Given: Total water = 18.75 liters
Total students =5
If each student in the group used the same amount of water for their experiment, then the quantity of the water received by each student = [tex]\dfrac{\text{Total quantity}}{\text{Total students}}[/tex]
[tex]=\dfrac{18.75}{5}\\\\=3.75\ liters[/tex]
The quantity of the water received by each student = 3.75 liters.
