Find each product or quotient where possible. See Example 2. -0.06(0.4)

검증된 단계별 안내

Identify the operation: The problem asks to find the product of two numbers, -0.06 and 0.4.

Recall the rule for multiplying decimals: Multiply the numbers as if they were whole numbers, then place the decimal point in the product according to the total number of decimal places in both factors.

Count the decimal places: -0.06 has 2 decimal places, and 0.4 has 1 decimal place, so the product will have 2 + 1 = 3 decimal places.

Multiply the numbers ignoring the signs and decimals: Multiply 6 by 4 to get 24.

Apply the decimal places and the sign: Place the decimal point to have 3 decimal places in the product, and since one factor is negative, the product will be negative.
