Answer 1

Respuesta:

$\frac{12}{15} + \frac{11}{45} = \frac{36}{45} + \frac{11}{45} = \frac{47}{45}$

$\frac{4}{9} + \frac{1}{12} = \frac{16}{36} + \frac{3}{36} = \frac{19}{36}$

$\frac{10}{12} + \frac{15}{4} = \frac{10}{12} + \frac{45}{12} = \frac{55}{12}$

$\frac{9}{14} + \frac{5}{2} = \frac{9}{14} + \frac{35}{14} = \frac{44}{14} = \frac{22}{7}$
