PORFA LO NECESITO.

Answer 1

$\texttt{Expresemos las fracciones}\\\texttt{como la parte entera} \\\texttt{mas una fracci\'on , es decir} \\1\frac{2}{5}=1+\frac{2}{5}\\3\frac{1}{5}=3+\frac{1}{5}\\\texttt{Simplificando aun mas las}\\\texttt{fracciones anteriores nos queda:}\\\\1+\frac{2}{5}=\frac{5}{5}+\frac{2}{5}=\\=\frac{7}{5}\\3+\frac{1}{5}=\frac{15}{5}+\frac{1}{5}=\frac{16}{5}\\\\\texttt{Finalmente simplificando todo }\\\texttt{se obtiene:} \\\\1+\frac{2}{5}+3=\\=\frac{7}{5}+3=\frac{7}{5}+\frac{15}{5}=\\=\frac{22}{5}\\\\3+\frac{1}{5}-8=\\=\frac{16}{5}-\frac{40}{5}=-\frac{24}{5}=\\=\frac{22}{5}*-\frac{24}{5}=\\=-\frac{528}{5}\\\\\texttt{As\'i:} \\\\1\frac{2}{5}+3*3\frac{1}{5}-8=\\=-\frac{528}{5}\\\\\texttt{SALUDOS.}$
