Me ayudan es urgente, doy votó, corazón, coronado, todo pero por favorrrrrr doy todo q esté bien ​

Answer 1

A) $-\frac{15}{23} + \frac{19}{23} = \frac{(-15)+19}{23} = \frac{4}{23}$

B) $(\frac{3}{4} + \frac{5}{3}) + (7 +\frac{1}{5}) = \frac{9+20}{12} + \frac{35+1}{5} = \frac{29}{12} + \frac{36}{5} = \frac{145+432}{60} = \frac{577}{60}$

C) $(-\frac{2}{5} + 4) - (-\frac{1}{3} + 1) = (\frac{-2 + 20}{5}) - (\frac{-1+3}{3})= \frac{18}{5} -\frac{2}{3} = \frac{54-10}{15}=\frac{44}{15}$

D) $(-\frac{3}{4} + \frac{5}{3}) - (-\frac{1}{3} + 1) = \frac{-9+20}{12} - \frac{-1+3}{3}= \frac{11}{12} - \frac{2}{3} = \frac{11-8}{12} = \frac{3}{12} = \frac{1}{4}$
