An algebra problem by Sai Prasath

Read slowly:

$8 \div$ by $\displaystyle \frac{1}{2}$ (half) $= 8\times2=\boxed{16}$

8 divided by half is similar to 8 multiplied by 2

$8 \div$ $\dfrac{1}{2}$ $= ?$

$\Rightarrow 8 \times 2 = 16$

$\frac{8}{\frac{1}{2}}$

= $8\times2$

=16

ITS SO SIMPLE. IT ACTUALLY MEANS MULTIPLY 8 BY2 BY DOING THAT,16 IS THE REQUIRED ANSWER

I calculated this mentally. It took me 2 seconds.
