Question

(2 целых 1/3- 1 целая 2/3*0.75):(-4 целых 1/3)-1/8

Answer 1

$1)1 \frac{2}{3} *0,75= \frac{5}{3} * \frac{3}{4} = \frac{5}{4} \\ 2)2 \frac{1}{3}- \frac{5}{4} = \frac{7}{3}- \frac{5}{4}= \frac{28-15}{12} = \frac{13}{12} \\ 3) \frac{13}{12} :(-4 \frac{1}{3} )= \frac{13}{12} * (-\frac{3}{13} )=- \frac{1}{4} \\ 4)- \frac{1}{4} - \frac{1}{8} =-( \frac{2+1}{8} )=- \frac{3}{8}$
