Answer:- 1

Explanation:-

Solution:

Let the missing number is x

\begin{aligned} Given, \\ \frac{20 + 8 \times 0.5}{20 - ?} = 12 \\ \Rightarrow \frac{20 + 4}{20 - 4} = 20 \\ \Rightarrow \frac{24}{20 - x} = 12 \\ \Rightarrow 20 - x = \frac{24}{12} \\ = 2 \\ \Rightarrow x = 20 - 2 \\ = 18 \\ Hence, \\ the number is 18 \end{aligned}

$\eqalign{ & {\text{Given,}} \cr & \frac{{20 + 8 \times 0.5}}{{20 - ?}}{\text{ = 12}} \cr & \Rightarrow \frac{{20 + 4}}{{20 - 4}} = 20 \cr & \Rightarrow \frac{{24}}{{20 - x}} = 12 \cr & \Rightarrow 20 - x = \frac{{24}}{{12}} \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = 2 \cr & \Rightarrow x = 20 - 2 \cr & \,\,\,\,\,\,\,\,\,\,\,\, = 18 \cr & {\text{Hence,}} \cr & {\text{the number is 18}} \cr}$
