Question

Verify and name of the property used.

$\left(-212\right)÷\left(-212\right)$

Answer 1

By using the division of a number by itself we get $1$

So,

$$\begin{gathered} \left(-212\right)÷\left(-212\right)=\frac{-212}{-212} \\ =1 \end{gathered}$$

Hence, the property used is division of number by itself.
