To determine if Miss Johnson's answer of 2.155664 for the division \( 3.04 / 7.091 \) is reasonable, we can perform the division and check the result.

First, let's estimate the quotient:

- \( 3.04 \) is approximately \( 3 \).
- \( 7.091 \) is approximately \( 7 \).

Now, dividing these estimates:

\[
\frac{3}{7} \approx 0.42857
\]

This tells us that the expected value of \( 3.04 / 7.091 \) should be around \( 0.43 \).

Now, let's compute the exact value of \( 3.04 / 7.091 \):

\[
\frac{3.04}{7.091} \approx 0.4287
\]

Miss Johnson's calculated answer of \( 2.155664 \) is much larger than what we estimated and calculated, suggesting her answer is not reasonable.

**Conclusion**: Miss Johnson's answer is not reasonable because the expected value of the division \( 3.04 / 7.091 \) is approximately \( 0.4287 \), not close to \( 2.155664 \).
