Solve the following: Select the rational numbers from the list which are also the integers.
9/4, 8/4, 7/4, 6/4, 9/3, 8/3, 7/3, 6/3, 5/2, 4/2, 3/1, 3/2, 1/1, 0/1, -1/1, -2/1, -3/2, -4/2, -5/2, -6/2

Solution:

Integers are just positive or negative numbers

Among the given set, 8/4 gives 2 which is an integer

9/3 = 3 which is an integer

6/3 = 2 which is an integer

4/2 = 2 which is an integer

3/1 = 3 which is an integer

1/1 = 1 which is an integer

0/1 = 0 which is an integer

-1/1 = -1 which is an integer

-2/1 = -2 which is an integer

-4/2 = -2 which is an integer

-6/2 = -3 which is an integer

The number 9/4 = 2.25, 7/4 = 1.75, 8/3 = 2.66, 7/3 = 2.33, 5/2 = 2.5,-3/2 = -1.5,-5/2 = -2.5 all give decimals as result

Hence, these numbers cannot be integers

Among the set 9/4, 8/4, 7/4, 6/4, 9/3, 8/3, 7/3, 6/3, 5/2, 4/2, 3/1, 3/2, 1/1, 0/1, -1/1, -2/1, -3/2, -4/2, -5/2, -6/2, out of these 11 rational numbers are integers.
