Question

Multiply: 2.7 × (–3) × (–1.2). A. –9.72 B. –10.8 C. 10.8 D. 9.72

Answer 1

D. 9.72

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.

Answer 2

Answer:
`\text{ D) } 9.72`

Explanation:

Here the give expression is,

`2.7 *(-3)* (-1.2)`

We can write,

`2.7 *(-3)* (-1.2) = 2.7 * 3.6` ( because
`-a* -b = ab`)

`2.7 *(-3)* (-1.2) = 9.72`

⇒ Option D is correct.
