Question

Name the property the equation illustrates. -2.1*1=-2.1

Multiplication Property of –1
Identity Property of Addition
Inverse Property of Multiplication
Identity Property of Multiplication

Answer 1

Answer: The correct option is 4th, i.e.,identity property of multiplication.

Step-by-step explanation:

It is given that
`-2.1* 1=-2.1`

correct option is identity property of multiplication.

Reason for correct option:

The identity property of multiplication states that if a real number multiplied by 1, then we gtet the same number.

`a* 1=a`

In the given equation -2.1 is multiplied by 1 and we get -2.1.

Reason for incorrect option:

It the given equation 1 is multiplied by -2.1, So the multiplication property of -1 is not used and first option is incorrect.

The given equation is a problem of multiplication, so identity property of addition is an incorrect option.

The inverse property of multiplication property states that the multiplication of a real number and its inverse is 1.

`a* b=1`

Since we don't have 1 on another side, so inverse property of multiplication is an incorrect option.
