[tex]b) 3\frac{6}{11} +2\frac{7}{11} = (3+2)+(\frac{6}{11} +\frac{7}{11} )= 5+\frac{13}{11} =[/tex]
[tex]5+1\frac{2}{11} = 6+\frac{2}{11} = 6\frac{2}{11}[/tex]
[tex]c) 5\frac{5}{9} +4\frac{5}{9} = 9+\frac{10}{9} = 9+1\frac{1}{9} =[/tex]
[tex]10+\frac{1}{9} = 10\frac{1}{9}[/tex]
[tex]d)3\frac{5}{13} +8\frac{10}{13} = 11+\frac{15}{13} = 11+1+\frac{2}{13} =[/tex]
[tex]12+\frac{2}{13} = 12\frac{2}{13}[/tex]
[tex]e)1\frac{3}{7} +2\frac{3}{7} +3\frac{3}{7} = 6+\frac{9}{7} =6+1+\frac{2}{7}=[/tex]
[tex]7+\frac{2}{7} = 7\frac{2}{7}[/tex]
[tex]f) 1\frac{5}{8} +9\frac{5}{8} +1\frac{7}{8} = 11+2+\frac{1}{8}=[/tex]
[tex]13+\frac{1}{8}=13\frac{1}{8}[/tex]
[tex]g)8\frac{3}{10}+4\frac{3}{10} +\frac{7}{10}=\frac{83}{10} +\frac{43}{10} +\frac{7}{10} = \frac{133}{10}[/tex]
[tex]h)\frac{7}{15} +3\frac{8}{15} +5\frac{11}{15} = \frac{7}{15}+\frac{53}{15} +\frac{86}{15} =\frac{146}{15}[/tex]
Mam nadzieję że dobrze... liczę na naj...
