16/24 + 15/20 + 12/18=

Answer 1

Respuesta:

[tex] \frac{5}{25} + \frac{3}{9} = \frac{1}{5} + \frac{1}{3} = \frac{3}{15} + \frac{5}{15} = \frac{8}{15} [/tex]

[tex] \frac{12}{16} - \frac{2}{5} = \frac{3}{4} - \frac{2}{5} = \frac{15}{20} - \frac{8}{20} = \frac{7}{20} [/tex]

[tex] \frac{18}{20} - \frac{1}{2} = \frac{9}{10} - \frac{1}{2} = \frac{9}{10} - \frac{5}{10} = \frac{4}{10} = \frac{2}{5} [/tex]

[tex] \frac{2}{6} + \frac{3}{9} + \frac{8}{12} = \frac{1}{3} + \frac{1}{3} + \frac{2}{3} = \frac{4}{3} [/tex]

[tex] \frac{16}{24} + \frac{15}{20} + \frac{12}{18} = \frac{2}{3} + \frac{3}{4} + \frac{2}{3} = \frac{6}{12} + \frac{9}{12} + \frac{8}{12} = \frac{23}{12} [/tex]
