Answer 1

$1);;frac1{not2}cdotfrac{not2}{not3}cdotfrac{not3}{not4}cdotfrac{not4}5=frac15\2);;frac6{not7}cdotfrac{not7}{not8}cdotfrac{not8}{not9}cdotfrac{not9}{not{10}}cdotfrac{not{10}}{11}=frac6{11}\3);;frac12cdotfrac23cdotldotscdotfrac{23}{24}cdotfrac{24}{25}=frac1{25}$
$4);;1frac12cdot1frac13cdot1frac14cdot1frac15=frac{not3}2cdotfrac{not4}{not3}cdotfrac{not5}{not4}cdotfrac6{not5}=frac62=3\5);;left(1+frac14right)cdotleft(1+frac15right)cdotleft(1+frac16right)cdotleft(1+frac17right)cdotleft(1+frac18right)=\=frac{not5}{4}cdotfrac{not6}{not5}cdotfrac{not7}{not6}cdotfrac{not8}{not7}cdotfrac{9}{not8}=frac94=2frac14$
$6);;left(1-frac12right)cdotleft(1-frac13right)cdotleft(1-frac14right)cdotldotscdotleft(1-frac1{99}right)cdotleft(1-frac1{100}right)=\=frac12cdotfrac23cdotfrac34cdotldotscdotfrac{98}{99}cdotfrac{99}{100}=frac1{100}=0,01$
