Answer:  \text{ D) } 9.72

Step-by-step explanation:

Here the give expression is,

2.7 \times(-3)\times (-1.2)

We can write,

2.7 \times(-3)\times (-1.2) = 2.7 \times 3.6  ( because -a\times -b = ab)

2.7 \times(-3)\times (-1.2) = 9.72

⇒ Option D is correct.

<u>Answer:</u>

D. 9.72

<u>Step-by-step explanation:</u>

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.

15+0= 15
Ksju [112]

First of all, let's take a look on the question.

\large{15 + 0 = 15}

Here, 0 is added to 15 and the resultant is 15 only. So, we can say that 0 when added with any number gives the same number as the resultant.

So, the property is known as <u>Identi</u><u>ty</u> property because 0 is added to get the identity of the same number.

<u>The Correct Option:</u>

\large{ \boxed{ \red{ \bf{Option \: C}}}}

So, let's know more...

  • Commutative property ➝ a + b = b + a
  • Associative property ➝ a + (b + c) = (a + b) + c
  • Distributive property ➝ a(b + c) = ab + ac

So this is the general form of these properties which is general observed in the rational numbers.
