Answer 2

Answer:

• A rational number between given numbers 72 and 73 is 72.5

Step-by-step explanation:

• A rational number between 72 and 73 is = 1/2(72+73)=72.5= 725/10

• The real numbers which can be written in the form p/q  where p and q are integers and q ≠ 0, are called Rational numbers.

• Between any two different rational numbers, there exist  many rational  numbers.  

• To Find a rational number between 72 and 73, the best way is to find their mean.

        So, (72 + 73)/2

        = 145/2= 72.5

      Hence , a rational number  between 72 and 73 is 72.5.

• Other rational numbers in between are:

      72 = 720/10   and 73 = 730/10

      721/10  , 722/10 , 723/10 , ....,  728/10 , 729/10
