Answer 1

Explicación paso a paso:

$(1 - \frac{1}{3} )\times (1 - \frac{1}{4} ) \times (1 - \frac{1}{5} )\times (1 - \frac{1}{6} ) =$

$( \frac{3}{3} - \frac{1}{3} )( \frac{4}{4} - \frac{1}{4} )( \frac{5}{5} - \frac{1}{5})( \frac{6}{6} - \frac{1}{6} ) =$

$\frac{2}{3} \times \frac{3}{4} \times \frac{4}{5} \times \frac{5}{6} = \frac{123}{360} = \frac{1}{3}$

ahora el denominador

3/4+4/3=9/12+16/12=25/12

4/5+5/4=16/20+25/20=41/20

25/12*20/41=540/492=125/123

1/3*123/125=123/375=41/125
