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:
$$\Large  q = \frac{{78}}{{10}} = 7.8$$
