Respuesta:
1) si son múltiplos porque 13x2=26
la fracción de los animales venenosos es 247/338 o 19/26
2)
A) 19/6
B) 33/18 o 11/6
C) 37/15
D) 33/27 o 11/9
Explicación paso a paso:
1)
[tex] \frac{8}{13} + \frac{3}{26} \\ = \frac{208}{338} + \frac{39}{338} \\ = \frac{247}{338} [/tex]
[tex] \frac{2}{3} + \frac{5}{2} \\ = \frac{4}{6} + \frac{15}{6} \\ = \frac{19}{6} [/tex]
[tex] \frac{4}{3} + \frac{3}{6} \\ = \frac{24}{18} + \frac{9}{18} \\ = \frac{33}{18} [/tex]
[tex] \frac{5}{3} + \frac{4}{5} \\ = \frac{25}{15} + \frac{12}{15} \\ = \frac{37}{15} [/tex]
[tex] \frac{5}{9} + \frac{2}{3} \\ = \frac{15}{27} + \frac{18}{27} \\ = \frac{33}{27} [/tex]
