Find a rational number between 3/5 and 4/5 ( see I just only want one so please don't give me all five)

goldenfox [79]

Answer:

$\dfrac{7}{10}$

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 :

$\dfrac{a+b}{2}$

We have, a = 3/5 and b = 4/5

So,

$\dfrac{\dfrac{3}{5}+\dfrac{4}{5}}{2}\\\\=\dfrac{\dfrac{7}{5}}{2}\\\\=\dfrac{7}{10}$

So, a rational number between 3/5 and 4/5 is equal to 7/10.
