For this case we must indicate the percentage that represents the following expression:
[tex]\frac {1} {20}[/tex]
By a rule of three we can solve them:
20 ----------> 100%
1 ------------> x
Where the variable x represents the percentage of 1 with a base of 20.
[tex]x = \frac {1 * 100} {20}\\x = 5[/tex]
So, we have that [tex]\frac {1} {20}[/tex] represents 5%
Answer:
Option A
