Answer:
Option D.
Step-by-step explanation:
A unit fraction is a rational number written as 1/n, where n is a positive integer.
We need to find a number or expression which is an integer multiple of the unit fraction 1/4. It means the number which is the product of an integer and 1/4.
[tex]\dfrac{1}{8}=\dfrac{1}{2}\times \dfrac{1}{4}[/tex]
1/8 is the product of 1/2 and 1/4. Here. 1/2 is not an integer.
[tex]\dfrac{1}{4}\times \dfrac{1}{4}[/tex]
It is the product of 1/4 and 1/4. Here. 1/4 is not an integer.
[tex]\dfrac{3.2}{4}=3.2\times \dfrac{1}{4}[/tex]
It is the product of 3.2 and 1/4. Here. 3.2 is not an integer.
[tex]\dfrac{3}{4}=3\times \dfrac{1}{4}[/tex]
It is the product of 3 and 1/4. Here. 3 is an integer.
Therefore, the correct option is D.
