The value of r of the given equation is 3. option B

Step-by-step explanation:

Given,

$\frac{1}{4} (r-\frac{5}{2} ) = \frac{1}{8}$

or, $r - \frac{5}{2} =(\frac{\frac{1}{8} }{\frac{1}{4} })$ [ $\frac{1}{4}$ will be dividing by $\frac{1}{8}$ ]

or, $r-\frac{5}{2}= \frac{1X4}{8X1}$

or, $r-\frac{5}{2} = \frac{1}{2}$

or, r = $\frac{1}{2} +\frac{5}{2}$

or, r = $\frac{6}{2}$

or, r = 3

Hence the value of r is 3.
