2)0.1:(-1/12)=
3)-4/9:1,6
помогите решить

Answer 1

$1)-0,12:left(1frac45right)=-frac{12}{100}:frac95=-frac{12}{100}cdotfrac59=-frac{4cdot1}{20cdot3}=\=-frac4{60}=-frac1{15}\ 2);0,1:left(-frac1{12}right)=-frac1{10}cdot12=-frac{10}{12}=-frac56\ 3);-frac49:1,6=-frac49:frac{16}{10}=-frac49cdotfrac{10}{16}=-frac19cdotfrac{10}4=-frac{1cdot5}{9cdot2}=-frac5{18}$
