Question

Вычислитель: (-5/12-3/4): 2 1/3+5 1/3*(умножить) 0,75=

Answer 1

$\frac{(- \frac{5}{12} - \frac{3}{4}) }{2 \frac{1}{3} } + 5\frac{1}{3}*0,75=3,5$

$1) - \frac{5}{12} - \frac{3}{4}=- \frac{-5-3*3}{12} =- \frac{14}{12} =- \frac{7}{6}$

$2) -\frac{7}{6} :2 \frac{1}{3} = -\frac{7}{6} : \frac{7}{3}= -\frac{7}{6} * \frac{3}{7}= -\frac{1}{2}$

$3) 5\frac{1}{3}* 0,75= \frac{16}{3}* \frac{75}{100} = 4$

$4) - \frac{1}{2} +4= -0,5+4=3,5$

$\frac{ (-\frac{5}{12}- \frac{3}{4} )}{ 2\frac{1}{3} +5 \frac{1}{3} *0,75} = -\frac{7}{38}$

$1) - \frac{5}{12} - \frac{3}{4}=- \frac{-5-3*3}{12} =- \frac{14}{12} =- \frac{7}{6}$

$2) 5\frac{1}{3}* 0,75= \frac{16}{3}* \frac{75}{100} = 4$

$3)2 \frac{1}{3}+4= \frac{7}{3} + \frac{4}{1}= \frac{19}{3}$

$4) -\frac{7}{6} : \frac{19}{3}= -\frac{7}{6} * \frac{3}{19} =- \frac{7}{38}$
