Answer:

7.8 is a rational number between 7.7 and 7.9.

Explanation:

there are infinite rational numbers between 7.7 and 7.9. 7.8 is rational. So is 7.88. And 7.888. And 7.8888. Their fractions are, respectively: 78/10, 788/100, 7888/1000, and 78888/10000. They can all be written as a fraction (between two integers), and so, they are rational.
