Question

x - 15% . x =1/3 

Answer 1

\(x-15\%.x=\frac{1}{3}\Rightarrow x-\frac{15}{100}.x=\frac{1}{3}\Rightarrow x-\frac{3}{20}.x=\frac{1}{3}\)

 \(\Rightarrow x.\frac{17}{20}=\frac{1}{3}\Rightarrow x=\frac{1}{3}:\frac{17}{20}=\frac{20}{51}\)

Answer 2

x - 15% = \(\frac{1}{3}\)

x - \(\frac{15}{100}\)= \(\frac{1}{3}\)

x = \(\frac{1}{3}+\frac{15}{100}\)

x = \(\frac{29}{60}\)
