вычислите 1)32/55+23/55 2)5/33+6/33 3)13/48-11/48

Ответ:

[tex]\dfrac{32}{55} + \dfrac{23}{55} = \dfrac{55}{55} = 1[/tex]

[tex]\dfrac{5}{33} + \dfrac{6}{33} = \dfrac{11}{33} = \dfrac{11:11}{33:11} =\dfrac{1}{3}[/tex]

[tex]\dfrac{13}{48} - \dfrac{11}{48} = \dfrac{2}{48} =\dfrac{2:2}{48:2} =\dfrac{1}{24}[/tex]
