-1/15+9/24
AYUDA

Answer 1

$\frac{2}{9}+ \frac{14}{18}= \\ \\ \frac{2}{9}+ \frac{7}{9}= \\ \\ \frac{9}{9}= \\ \\ 1$
______________________________________________________________
$- \frac{5}{7}+ \frac{3}{9}= \\ \\ - \frac{5}{7}+ \frac{1}{3}= \\ \\ \frac{-15+7}{21} = \\ \\ - \frac{8}{21}$ 
______________________________________________________________
$\frac{4}{32}+ \frac{5}{24} = \\ \\ \frac{1}{8}+ \frac{5}{24}= \\ \\ \frac{3+5}{24}= \\ \\ \frac{8}{24} = \\ \\ \frac{1}{3}$ 
_____________________________________________________________
$\frac{12}{25} + \frac{8}{45} = \\ \\ \frac{9+5}{225}= \\ \\ \frac{14}{225}$
_____________________________________________________________
$\frac{4}{17}+ \frac{6}{46}= \\ \\ \frac{17}{4}+ \frac{3}{23} = \\ \\ \frac{391+12}{92} = \\ \\ \frac{403}{92}$
_____________________________________________________________
$- \frac{1}{15}+ \frac{9}{24}= \\ \\ - \frac{1}{15}+ \frac{3}{8} = \\ \\ \frac{-8+45}{120}= \\ \\ \frac{37}{120}$
