first part: we have to search for a rational number q, such that: 7.7< q < 7.9 Now I note that: 7.7=77/10, and 7.9=79/10, so I have to search for a rational number q such that the equivalent condition holds: $\Large \frac{{77}}{{10}} < q < \frac{{79}}{{10}}$ a possible choice for q, is: $\Large q = \frac{{78}}{{10}} = 7.8$

it is the answer to the first part, since we have to find an irrational number
