номер 635 решите пожалуйста

Answer 1

$1);frac{left|frac49-frac56right|cdotleft|frac{11}{14}+frac12right|}{(-1,2)cdotleft|frac16-frac18right|}=frac{left|frac8{18}-frac{15}{18}right|cdotleft|frac{11}{14}+frac7{14}right|}{(-1,2)cdotleft|frac4{24}-frac3{24}right|}=frac{left|-frac7{18}right|cdotleft|frac{18}{14}right|}{(-1,2)cdotleft|frac1{24}right|}=frac{frac7{18}cdotfrac{18}{14}}{left(-frac{12}{10}right)cdotfrac1{24}}=\=frac{frac12}{left(-frac1{20}right)}=-frac12cdotfrac{10}1=-5$

$2);frac{left|frac5{12}-frac4{15}right|cdotleft|frac1{18}+frac12right|}{left|frac23-frac58right|cdot(-8)}=frac{left|frac{25}{60}-frac{16}{60}right|cdotleft|frac1{18}+frac9{18}right|}{left|frac{16}{24}-frac{15}{24}right|cdot(-8)}=frac{left|frac9{60}right|cdotleft|frac{10}{18}right|}{left|frac1{24}right|cdot(-8)}=frac{frac9{60}cdotfrac{10}{18}}{frac1{24}cdot(-8)}=\=frac{frac1{12}}{left(-frac13right)}=-frac1{12}cdot3=-frac14$
