Question

(5/12-1/4*2/3):3/4+1/2

Answer 1

$(frac{5}{12} - frac{1}{4}* frac{2}{3})/ frac{3}{4}+ frac{1}{2}$
$1) frac{1}{4}* frac{2}{3}= frac{1}{6}$
$2) frac{5}{12} - frac{1}{6}= frac{5}{12} - frac{2}{12}= frac{3}{12} = frac{1}{4}$
$3) frac{1}{4}/ frac{3}{4}= frac{1}{4}* frac{4}{3}= frac{1}{3}$
$4) frac{1}{3} + frac{1}{2}= frac{2}{6}+frac{3}{6}= frac{5}{6}$

Answer 2

1).1/4·2/3=1/2·1/3=1/6
2).5/12-1/6=5/12-2/12=3/12=1/4
3).1/4:3/4=1/4·4/3=1·1/3=1/3
4).1/3+1/2=2/6+3/6=5/6
Ответ: 5/6
