Answer:

5.48, 78.541 and 97

Explanation:

A rational number by definition refers to a number that is in the form of k/m and in which k and m are integers and m is not equal to 0.

Let me give you some examples:

  • 1/3
  • 2/4
  • 1/5
  • 9/3

From our question,

  • 5.48 = 137/25 hence rational number
  • 78.541 = 78541/1000; rational
  • 97 = 97/1; rational
  • 42.111..... = 4211111*/100000: irrational number. It is recurring hence not a rational number.

Therefore 5.48, 78.541 and 97 are rational numbers
