Part A: Find a rational number that is between 3.7 and 3.9. Explain why it is rational.

Part B: Find an irrational number that is between 3.7 and 3.9. Explain why it is irrational. Include the decimal approximation of the irrational number to the nearest hundredth.

Respuesta :

 between 3.7 and 3.9


   =37 / 10   &  39 / 10    ( we multiply the numerator and denominator of both                numbers )

   = 38 / 10                     (  38 / 10  or  3.8   is a rational number between 3.7 and 3. 9)

   =  3. 8
