!!!!!!ТЕРМІНОВО ДАМ 20 БАЛІВ!!!!!!!​

а) -3,4 × 2,7 = -9,18

б) [tex]\frac{11}{14} * (-\frac{21}{44}) = -\frac{11*21}{14*44} = -\frac{1*21}{14*4} = -\frac{21}{56}[/tex]

в) [tex]36 : (-\frac{4}{13}) = \frac{36}{1} : (-\frac{4}{13}) = -\frac{36*13}{1*4} = -\frac{9*13}{1*1} = -\frac{117}{1} = -117[/tex]

г) [tex]-3\frac{3}{13} : (-2\frac{11}{26}) = -\frac{42}{13} : (-\frac{63}{26}) = \frac{42*26}{13*63} = \frac{42*2}{1*63} = \frac{84}{63} = \frac{4}{3} = 1\frac{1}{3}[/tex]
