Answer 1

(-0,76-0,44):$2 \frac{2}{3}$=-1,2:$\frac{8}{3}$=-$\frac{6}{5} : \frac{8}{3} =- \frac{6*3}{5*8} = -\frac{3*3}{5*4} =- \frac{9}{20}$=-0,45
$(3 \frac{5}{14}-2\frac{3}{4} )*(-3\frac{5}{17}) = (\frac{47}{14}-\frac{11}{4} )*(-\frac{56}{17})=(\frac{94}{28}-\frac{77}{28})*(-\frac{56}{17} )=$$\frac{17}{28}*(-\frac{56}{17} )=- \frac{17*56}{28*17} = -2$
