Answer 1

Dear student
$$\begin{gathered} \mathrm{Let}\mathrm{the}\mathrm{required}\mathrm{number}\mathrm{be}\mathrm{x}. \\ \mathrm{So},\mathrm{A}.\mathrm{T}.\mathrm{Q} \\ \mathrm{x}\times 2.3=1.56 \\ \Rightarrow \mathrm{x}=\frac{1.56}{2.3} \\ \Rightarrow \mathrm{x}=\frac{156\times 10}{23\times 100} \\ \Rightarrow \mathrm{x}=\frac{156}{230} \\ \Rightarrow \mathrm{x}=\frac{78}{115} \\ \Rightarrow \mathrm{x}=0.678 \\ \mathrm{So},\mathrm{the}\mathrm{required}\mathrm{number}\mathrm{is}0.678 \end{gathered}$$
