Answer:
[tex]\dfrac{26}{155}[/tex], [tex]\dfrac{27}{155}[/tex], and [tex]\dfrac{28}{155}[/tex].
Step-by-step explanation:
What is a rational number? By definition, a rational number can be represented as the fraction of two integers.
The goal is to find three fractions in the form [tex]\dfrac{p}{q}[/tex] between [tex]\dfrac{5}{31}[/tex] and [tex]\dfrac{6}{31}[/tex].
[tex]\dfrac{5}{31} < \dfrac{p}{q} < \dfrac{6}{31}[/tex].
At this moment, there doesn't seems to be a number that could fit. The question is asking for three of these numbers. Multiple the numerator and the denominator by a number greater than three (e.g., five) to obtain
[tex]\dfrac{25}{155} < \dfrac{p}{q} < \dfrac{30}{155}[/tex].
Since [tex]p[/tex] and [tex]q[/tex] can be any integers, let [tex]q = 155[/tex].
[tex]\dfrac{25}{155} < \dfrac{p}{155} < \dfrac{30}{155}[/tex].
[tex]\implies 25 < p < 30[/tex].
Possible values of [tex]p[/tex] are 26, 27, and 28. That corresponds to the fractions
[tex]\dfrac{26}{155}[/tex], [tex]\dfrac{27}{155}[/tex], and [tex]\dfrac{28}{155}[/tex].
These are all rational numbers for they are fractions of integers.
