Answer 1

Respuesta:

21/21 = 1

22/9

7/15

12/18

24/14

Explicación paso a paso:

[tex]\frac{6}{7}[/tex] + [tex]\frac{3}{21}[/tex] = [tex]\frac{18+3}{21}[/tex]= [tex]\frac{21}{21}[/tex] = 1

[tex]\frac{4}{9} + \frac{6}{3} =\frac{4+18}{9} = \frac{22}{9}[/tex]

[tex]\frac{2}{5} + \frac{1}{15} = \frac{6+1}{15}=\frac{7}{15}[/tex]

[tex]\frac{5}{9}+ \frac{2}{18} = \frac{10+2}{18} =\frac{12}{18}[/tex]

[tex]\frac{8}{7} + \frac{8}{14} =\frac{16+8}{14} =\frac{24}{14}[/tex]
