Find each product or quotient where possible. See Example 2. -7.2/0.8

Guida verificata passo dopo passo

Identify the operation to be performed. The problem asks to find the product of -7.2 and 0.8, which means we need to multiply these two numbers.

Recall that multiplication of two numbers is done by multiplying their absolute values and then applying the sign rules. Since one number is negative and the other is positive, the product will be negative.

Set up the multiplication expression as \(-7.2 \times 0.8\).

Multiply the absolute values: calculate \(7.2 \times 0.8\) by treating them as decimal numbers.

Apply the negative sign to the result from step 4 to get the final product.
