Question

Write five rational number between 1/3 and 1/5

Answer 1

according to the above formulae

$= \frac{ \frac{1}{3} - \frac{1}{5} }{5 + 1} \\ \\ = \frac{ \frac{2}{15} }{6} \\ \\ = \frac{1}{45 } \\ \\ \\ \\ \\ \\ no.s = ( \frac{1}{ 3} + \frac{5}{45} )( \frac{1}{ 3} + \frac{2}{45} )( \frac{1}{ 3} + \frac{3}{45} )( \frac{1}{ 3} + \frac{4}{45} )( \frac{1}{ 3} + \frac{4}{45} )( \frac{1}{ 3} + \frac{5}{45} ) \\ \\ \\ = \frac{16}{45} . \frac{17}{45} . \frac{18}{45} . \frac{19}{45} . \frac{20}{45}$
