2. a:

\begin{gathered}(-\frac{8}{5})+(-\frac{6}{3} )=\frac{24+30}{15} =-\frac{54}{15} \\\\Simplificado:\\\\-\frac{18}{5}\\\\Mixto:\\\\-3\frac{3}{5}\end{gathered}(−58)+(−36)=1524+30=−1554Simplificado:−518Mixto:−353

2. b:

\begin{gathered}(-\frac{2}{4})+\frac{3}{4} =\frac{8+12}{16} =\frac{20}{16} \\\\Simplificado:\\\\\frac{5}{4}\\\\Mixto:\\\\1\frac{1}{4}\end{gathered}(−42)+43=168+12=1620Simplificado:45Mixto:141

2. c:

\begin{gathered}\frac{8}{9} +\frac{10}{6} =\frac{48+90}{54} =\frac{138}{54} \\\\Simplificado:\\\\\frac{23}{9} \\\\Mixto:\\\\2\frac{5}{9}\end{gathered}98+610=5448+90=54138Simplificado:923Mixto:295

2. d:

\begin{gathered}\frac{3}{2} +(-\frac{2}{8} )=\frac{24+4}{16} =\frac{20}{16} \\\\Simplificado:\\\\\frac{5}{4} \\\\Mixto:\\\\1\frac{1}{4}\end{gathered}23+(−82)=1624+4=1620Simplificado:45Mixto:141

3. a:

\begin{gathered}\frac{9}{2}\times \frac{-2}{3} =\frac{-18}{6} \\\\Simplificado:\\\\\frac{-3}{1} \\\\Mixto:\\\\-3\end{gathered}29×3−2=6−18Simplificado:1−3Mixto:−3

3. b:

\begin{gathered}\frac{15}{7}\times \frac{-6}{12} =\frac{-90}{84} \\\\Simplificado:\\\\\frac{-15}{14} \\\\Mixto:\\\\-1\frac{1}{14}\end{gathered}715×12−6=84−90Simplificado:14−15Mixto:−1141

3. c:

\begin{gathered}\frac{-8}{14}\times \frac{7}{6} =-\frac{56}{84} \\\\Simplificado:\\\\-\frac{2}{3}\end{gathered}14−8×67=−8456Simplificado:−32

3. d:

\begin{gathered}\frac{-1}{5} \times \frac{-19}{11} =\frac{19}{55} \\\end{gathered}5−1×11−19=5519

3. e:

\begin{gathered}\frac{-5}{18} \times \frac{-4}{9} =\frac{9}{162} \\\\Simplificado:\\\\\frac{1}{18}\end{gathered}18−5×9−4=16
