=> All of the options are correct.
Step-by-step explanation:
a rational number is a number that can be shown as the quotient of two integers a and b(the denominator b must not be equal to zero).
10/19 => a = 10, b = 19 (correct)
85/74 => a = 85, b = 74 (correct)
-48 => a = -48, b = 1 (correct)
-57 =>a = -57, b = 1 (correct)
=> All of the options are correct.
Hope this helps!
