Simplify ${{16}^{-\tfrac{1}{2}}}\times {{4}^{-\tfrac{1}{2}}}\times {{27}^{\tfrac{1}{3}}}$

Option A: 

$\tfrac{3}{8}$

Option B: 

$\tfrac{2}{3}$

Option C: 

$\tfrac{3}{4}$

Option D: 

$\tfrac{3}{2}$

Jamb Maths Solution: 

$\begin{align}  & {{16}^{-\tfrac{1}{2}}}\times {{4}^{-\tfrac{1}{2}}}\times {{27}^{\tfrac{1}{3}}}=\frac{1}{{{16}^{\tfrac{1}{2}}}}\times \frac{1}{{{4}^{\tfrac{1}{2}}}}\times {{27}^{\tfrac{1}{3}}} \\ & {{16}^{-\tfrac{1}{2}}}\times {{4}^{-\tfrac{1}{2}}}\times {{27}^{\tfrac{1}{3}}}=\frac{1}{\sqrt{16}}\times \frac{1}{\sqrt{4}}\times \sqrt[3]{27} \\ & {{16}^{-\tfrac{1}{2}}}\times {{4}^{-\tfrac{1}{2}}}\times {{27}^{\tfrac{1}{3}}}=\frac{1}{4}\times \frac{1}{2}\times 3=\frac{3}{8} \\\end{align}$
