Answer 1

Respuesta:

• $\frac{5}{9} + \frac{3}{9} = \frac{5 + 3}{9} = \frac{8}{9}$

• $\frac{2}{8} + \frac{1}{8} = \frac{2+1}{8} = \frac{3}{8}$

• $\frac{6}{24} +\frac{8}{24} =\frac{6+8}{24}=\frac{14}{24}$

• $\frac{3}{10}+\frac{5}{10}= \frac{3+5}{10} =\frac{8}{10}$

• $\frac{1}{9}+\frac{1}{9}=\frac{1+1}{9}=\frac{2}{9}$

• $\frac{2}{21} +\frac{2}{21} =\frac{2+2}{21}=\frac{4}{21}$

• $\frac{2}{5}+\frac{8}{9} +\frac{1}{9} =\frac{2}{5} +\frac{8+1}{9} =\frac{2}{5} +\frac{9}{9} =\frac{2*9+5*9}{5*9}=\frac{18+45}{45} =\frac{63}{45}$

• $\frac{1}{6}+\frac{10}{3}+\frac{5}{2}=\frac{1*3+6*10}{6*3}+\frac{5}{2}=\frac{63}{18}+\frac{5}{2}=\frac{63*2+18*5}{18*2}=\frac{216}{36}$
