enter your response here%.
To find the percent decrease, we first need to calculate the difference in water level:
Initial water level: 6 cm
Final water level: 3 cm
Decrease in water level = 6 cm - 3 cm = 3 cm
Next, we need to calculate the percent decrease:
Percent decrease = (Decrease in water level / Initial water level) * 100
Percent decrease = (3 cm / 6 cm) * 100
Percent decrease = 0.5 * 100 = 50%
Therefore, the percent decrease of water in the tank is 50%.
