Identify all sets to which the number - 3/4 belongs

b. odd numbers, whole numbers, integers, rational number

c. whole numbers, integers, rational number

a. rational numbers

Step-by-step explanation:

we observe that - 3/4 is a proper fraction (i. e it is a rational number)

hence

1) It cannot be a whole number

2) it cannot be an integer

therefore any answer choices that mention whole number or integer is not correct. By default, only a is correct.
