a ÷ (-1) = -a. State whether the statements are true or false

Solution:

The given expression is a ÷ (-1) = -a.

Now let us put the integer rules to prove whether the given statement is true or false

Therefore, using the integer rules and additive inverse rule, we observed that a ÷ (-1) = -a is a true fact. Hence it is a true statement.

✦ Try This: State whether the statement is true or false. 78 ÷ (-1) = -78.

We can apply integer rules and additive inverse rules to identify whether 78 ÷ (-1) = -78 is true or false
