To find the answer to the equation 800 * 0.25, you need to perform the operation of multiplication.

Start by multiplying the whole number, 800, by the decimal, 0.25.

To multiply a whole number by a decimal, you can follow these steps:
1. Ignore the decimal point for now and multiply the whole numbers as if they were both whole numbers. Multiply 800 by 25:
800 * 25 = 20000.

2. Now consider the decimal point. Count the number of decimal places in the decimal, which in this case is 0.25. There are two decimal places, so move the decimal point two places to the left in the result:
20000.00.

Therefore, 800 * 0.25 = 20000. Answer: 20000.
