Answer:
[tex]\dfrac{7}{10}[/tex]
Step-by-step explanation:
We need to find a rational number between 3/5 and 4/5.
We can find a rational number between two fractions as :
[tex]\dfrac{a+b}{2}[/tex]
We have, a = 3/5 and b = 4/5
So,
[tex]\dfrac{\dfrac{3}{5}+\dfrac{4}{5}}{2}\\\\=\dfrac{\dfrac{7}{5}}{2}\\\\=\dfrac{7}{10}[/tex]
So, a rational number between 3/5 and 4/5 is equal to 7/10.
