Question

simplify 3/4(1+1/3)(1+2/3)(1-2/5)(1+6/7)(1-12/13)​

Answer 1

$\frac{3}{4} (1 + \frac{1}{3} )(1 + \frac{2}{3} )(1 - \frac{2}{5} )(1 + \frac{6}{7} )(1 - \frac{12}{13} \\ = > \frac{3}{4} ( \frac{4}{3} )( \frac{5}{3} ) (\frac{3}{5} )( \frac{13}{7} )( \frac{1}{13} ) \\ = > \frac{3}{4} \times \frac{4}{3} \times \frac{5}{3} \times \frac{3}{5} \times \frac{13}{7} \times \frac{1}{13} \\ = > \frac{1}{7}$
