-2.1 × 1 = -2.1

Question

Name the property the equation illustrates

Answer 1

The equation \(-2.1 \times 1 = -2.1\) illustrates the **Multiplicative Identity Property**.

This property states that any number multiplied by 1 remains unchanged. In mathematical terms, for any real number \(a\),

\[ a \times 1 = a \]

In this case, \(-2.1\) is the number, and when it is multiplied by 1, it remains \(-2.1\).
