Question

Fill in the blanks (by trial and error method).

$8\times \square =32$

Answer 1

Trial and error method is a method in which we randomly substitute values until we get the desired value

$$\begin{gathered} 8\times 1=8\mathrm{and}8\ne 32. \\ 8\times 2=16\mathrm{and}16\ne 32. \\ 8\times 3=24\mathrm{and}24\ne 32. \\ 8\times 4=32\mathrm{and}32=32. \end{gathered}$$

Hence , $4$is the right answer.
