Answer 1

To make the expression \( m + [?] - 1.1 \) equivalent to \( m - 1.1 \), we can use the Identity Property of Addition, which states that adding zero to any number does not change its value.

Let's set up the equation:

\[
m + [?] - 1.1 = m - 1.1
\]

To isolate the bracketed term, we can rearrange it:

\[
m + [?] = m - 1.1 + 1.1
\]

Simplifying the right side:

\[
m + [?] = m
\]

Now, subtract \( m \) from both sides:

\[
[?] = 0
\]

Therefore, the number that makes the expression equivalent is:

**0**
