Mong Mn giúp em ạ em đang cần gấp lắm ạ hứa vote5* và ctlhn ạ

a)$\frac{-3}{5}$-(-$\frac{5}{17}$)+ (-$\frac{2}{5}$)

= $\frac{-51+25-34}{85}$

= $\frac{-60}{85}$

= $\frac{-12}{17}$

b)$\frac{5}{18}$-(-$\frac{1}{18}$) -$\frac{8}{24}$

= $\frac{20+4-24}{72}$

= $\frac{0}{72}$=0

c)(0,75-$\frac{5}{6}$ ):($\frac{-4}{7}$ + $\frac{1}{3}$)

= ($\frac{3}{4}$-$\frac{5}{6}$ ): $\frac{-12+7}{21}$

= $\frac{9-10}{12}$. $\frac{21}{-5}$

= $\frac{-1}{12}$. $\frac{21}{-5}$

= $\frac{7}{20}$

d)40%. $\frac{2}{3}$+4 $\frac{1}{3}$. $\frac{2}{5}$

=0.4. $\frac{2}{3}$+ $\frac{26}{15}$

= $\frac{8}{30}$+ $\frac{52}{30}$

=2

e)2 $\frac{3}{4}$+($\frac{-3}{5}$+ $\frac{1}{3}$):  $\frac{-4}{9}$

=$\frac{11}{4}$+ $\frac{-9+5}{15}$: $\frac{-4}{9}$

= $\frac{11}{4}$+  $\frac{9}{15}$

=  $\frac{165+36}{60}$

= $\frac{67}{20}$

g)(1+ $\frac{2}{3}$- $\frac{1}{4}$).($\frac{4}{5}$-$\frac{3}{4}$)

=$\frac{12+8-3}{12}$. $\frac{16-15}{20}$

= $\frac{17}{12.20}$=  $\frac{17}{240}$
