Question

(4 5/12:44 1/6-2,6):7,5-2,25×2 4/9

Answer 1

$left(4frac5{12}:44frac16-2,6right):7,5-2,25cdot2frac49=left(frac{53}{12}:frac{265}6-2frac6{10}right):7frac12-2frac14cdot2frac49=\=left(frac{53}{12}cdotfrac6{265}-frac{26}{10}right):frac{15}2-frac94cdotfrac{22}9=left(frac1{10}-frac{26}{10}right)cdotfrac2{15}-frac{11}2=-frac{25}{10}cdotfrac2{15}-frac{11}2=\=-frac13-frac{11}2=-frac26-frac{33}6=-frac{35}6=-5frac56$
