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
