Solution B
\(\frac{1}{5}*(\frac{1}{5} - \frac{1}{4})\)
\(\frac{1}{5}*(\frac{4}{20} - \frac{5}{20})\)
\(\frac{1}{5}*\frac{-1}{20}\)
\(\frac{-1}{100}\)
= Answer.
\(\frac{1}{5}*(\frac{1}{5} - \frac{1}{4})\)
\(\frac{1}{5}*(\frac{4}{20} - \frac{5}{20})\)
\(\frac{1}{5}*\frac{-1}{20}\)
\(\frac{-1}{100}\)
= Answer.
