Question

Which of the following sets contain only rational numbers that are integers?

F
(6, -3, 1.25}
G
(8, 4, 0.5)
H
(-8, 4/3,✔️16, 25)
J
(16/4,-8, 7, √5)

Answer 1

The set that contains only rational numbers that are integers is:

H: (-8, 4/3, 16, 25)

The number -8 is an integer, 16 and 25 are also integers, and 4/3 is a rational number, but not an integer.

The other sets contain numbers that are not integers or are not rational:

F: contains the rational number 1.25, which is not an integer.

G: contains the rational number 0.5, which is not an integer.

J: contains the irrational number √5, which is not rational and not an integer.
