Answer 2

Answer:

b = $\frac{1}{24}$

Step-by-step explanation:

Given,

A vary Inversely,

i.e,  a = $\frac{K}{b}$

      If a=1/2  and  b=1/3

Then,

    ⇒ $\frac{1}{2} = \frac{K}{\frac{1}{3} }$

   ⇒ $\frac{1}{2}=3K$

    ∴  $K=\frac{1}{6}$

Now,

If a = 4

Then,

  ⇒  a = $\frac{K}{b}$

  ⇒  $4 = \frac{\frac{1}{6} }{b}$

  ⇒ $4 = \frac{1}{6b}$

    ∴  $b = \frac{1}{24}$
