Question

пж помогите!!!!!!!!!​

Answer 1

-4$\frac{5}{7}$+(-5$\frac{4}{7}$)=-9$\frac{9}{7}$=-10$\frac{2}{7}$

-2,6+(-3,4)+(-5)=-6+(-5)=-11

-5,9+6,2=0,3

$\frac{7}{15}$+(-$\frac{19}{20}$)=$\frac{28}{60}$+(-$\frac{57}{60}$)=-$\frac{29}{60}$

-3$\frac{7}{12}$+(-4$\frac{11}{16}$)=-3$\frac{28}{48}$+(-4$\frac{33}{48}$)=-7$\frac{61}{48}$=-8$\frac{13}{48}$

-3$\frac{7}{9}$+4$\frac{2}{3}$=-3$\frac{7}{9}$+4$\frac{6}{9}$=$\frac{8}{9}$
