Denominator is the number which appears at the
bottom of fraction so the fraction we want is in the form X/8 and also less
than 5/6
Lets start from changing the values of X from
1.
1/8 = 0.125 and 5/6 = 0.8333
2/8 = 0.25
3/8 = 0.375
4/8 = 0.5
5/8 = 0.625
6/8 = 0.75
7/8 = 0.875, this is greater than 5/6
<span>So, the fractions with denominator 8 and less
than 5/6 are 1/8, 2/8, 3/8, 4/8, 5/8 and 6/8</span>

Answer:
C. 1/(4a)
Step-by-step explanation:
We assume you're comparing the vertex form ...
y = a(x -h)^2 +k
to the form used to write the equation in terms of the focal distance p.
y = 1/(4p)(x -h)^2 +k
That comparison tells you ...
a = 1/(4p)
p = 1/(4a) . . . . . . multiply by p/a; matches choice C

<em>Additional comment</em>
When using plain text to write a rational expression, parentheses are needed around any denominator that has is more than a single constant or variable. The order of operations requires 1/4a to be interpreted as (1/4)a. The value of p is 1/(4a).
When rational expressions are typeset, the fraction bar serves as a grouping symbol identifying the entire denominator:
