Question

А)3 целых 2/3 +1,1 ; б) 2/5 - 0,3 ; в)1 целая 3/11 * (-2,2) ; г) (-0,9) : 2 целых 1/4

Answer 1

$1) 3\frac{2}{3} +1.1 = \frac{9+2}{3}+\frac{11}{10}=\frac{11*10}{30}+\frac{11*3}{30}=\frac{143}{30}=4\frac{23}{30}$

$2)\frac{2}{5}-\frac{3}{10}=\frac{4-3}{10}=0,1$

$3)\frac{14}{11} * -\frac{22}{20}=-\frac{7}{5}$

$4)-\frac{9}{10}:\frac{9}{4}=-\frac{2}{5}$
