Question

Use the identity property to find the number that makes the expression m + [?] - 1.1 equivalent to m - 1.1

Answer 1

The identity property states that any number added or subtracted by zero remains the same. Therefore, to make the expression m + [?] - 1.1 equivalent to m - 1.1, the number that should be filled in the placeholder is 0.

So, m + 0 - 1.1 is equivalent to m - 1.1.
