Multiply: 2.7 × (–3) × (–1.2). a. –9.72 b. –10.8 c. 10.8 d. 9.72

D. 9.72

Step-by-step explanation:

We are given the following expression and we are to multiply it:

2.7 × (–3) × (–1.2)

Multiplying 2.7 and (–3) , starting from the left to get:

2.7 × (–3) = –8.1

Then multiplying this product with (–1.2) to get:

–8.1 × (–1.2) = 9.72

Since both of the terms were negative here so when negative is multiplied with another negative, it becomes positive.

Therefore, the correct option is D. 9.72.
