At noon, a tank contained 8 in. of water. After several hours, it contained 6 in. of water. What is the percent decrease of water in the tank?
The percent decrease of water in the tank is [ ].

Answer

To find the percent decrease, use the formula:

Percent Decrease = ((Original Amount - New Amount) / Original Amount) * 100%

Original Amount = 8 in.

New Amount = 6 in.

Percent Decrease = ((8 - 6) / 8) * 100% = (2 / 8) * 100% = 0.25 * 100% = 25%

The percent decrease of water in the tank is 25%.
