Answer: Option 'B' is correct.
Step-by-step explanation:
Since we have given that
A. The product of 3/4 and a number is 16.
The expression would be
[tex]\dfrac{3}{4}\times x=16[/tex]
B. 1/5 of a number
The expression would be
[tex]\dfrac{1}{5}x[/tex]
C. half of a number is 15
The expression would be
[tex]\dfrac{1}{2}x=15[/tex]
D. The difference of 20 and a number is 14
The expression would be
[tex]20-x=14[/tex]
So, we can see that [tex]\dfrac{1}{5}x[/tex] is represented by a single expression.
Hence, option 'B' is correct.
