Question

Q. Why 25*1/25 was changed to 25+1/25 ? why not 126/25?


$$\begin{gathered} x+\frac{1}{x}=25\frac{1}{25} \\ \Rightarrow x+\frac{1}{x}=25+\frac{1}{25} \end{gathered}$$

Answer 1

Dear Student,

$$\begin{gathered} 25\frac{1}{25}=\frac{625+1}{25}=\frac{626}{25},\mathrm{it}\mathrm{is}\mathrm{not}\mathrm{equal}\mathrm{to}\frac{126}{25} \\ \mathrm{And}\mathrm{we}\mathrm{changed}, \\ 25\frac{1}{25}\mathrm{to}25+\frac{1}{25}. \\ \mathrm{So},\mathrm{that}\mathrm{we}\mathrm{can}\mathrm{compare}\mathrm{LHS}\mathrm{and}\mathrm{RHS}. \end{gathered}$$
