82.78 ____=72.8464

To find the missing value that can be inserted in the blank, we can set up the following equation:

\[
82.78 \times x = 72.8464
\]

To solve for \( x \), divide both sides by 82.78:

\[
x = \frac{72.8464}{82.78}
\]

Calculating that gives:

\[
x \approx 0.880
\]

So,

\[
82.78 \times 0.880 \approx 72.8464
\]

Therefore, the missing value is approximately **0.880**.
