Final answer:
To find a value when 20% of a is 11, divide 11 by 0.20 to get a = 55.
Step-by-step explanation:
To find a value when 20% of a is 11, we can set up an equation. Let's represent the unknown value as 'a'. We know that 20% of 'a' is equal to 11, so we can write it as:
0.20a = 11
To solve for 'a', we can divide both sides of the equation by 0.20:
a = 11 / 0.20 = 55.
Therefore, a is 55.
