Ответ:
Привет! Давай помогу тебе с этими примерами. Будем решать их по порядку.
1) 26\frac{19}{25}+35\frac{1}{25} = (26 + 35) + (\frac{19}{25} + \frac{1}{25}) = 61 + \frac{20}{25} = 61 + \frac{4}{5} = 61\frac{4}{5}
2) 19\frac{6}{17}+29 = (19 + 29) + \frac{6}{17} = 48 + \frac{6}{17} = 48\frac{6}{17}
3) 203\frac{19}{41}-40\frac{6}{41} = (203 - 40) + (\frac{19}{41} - \frac{6}{41}) = 163 + \frac{13}{41} = 163\frac{13}{41}
4) 7\frac{7}{8}+59\frac{7}{8} = (7 + 59) + (\frac{7}{8} + \frac{7}{8}) = 66 + \frac{14}{8} = 66 + 1\frac{6}{8} = 66 + 1\frac{3}{4} = 67\frac{3}{4}
5) 35\frac{10}{13}-25\frac{12}{13} = (35 - 25) + (\frac{10}{13} - \frac{12}{13}) = 10 - \frac{2}{13} = 9\frac{13}{13} - \frac{2}{13} = 9\frac{11}{13}
6) 506\frac{9}{13}-72 = (506 - 72) + \frac{9}{13} = 434 + \frac{9}{13} = 434\frac{9}{13}
7) 29-18\frac{27}{30} = (29 - 18) - \frac{27}{30} = 11 - \frac{27}{30} = 10\frac{30}{30} - \frac{27}{30} = 10\frac{3}{30} = 10\frac{1}{10}
8) 19\frac{13}{49}-16 = (19 - 16) + \frac{13}{49} = 3 + \frac{13}{49} = 3\frac{13}{49}
9) 4\frac{4}{15}-1\frac{9}{15} = (4 - 1) + (\frac{4}{15} - \frac{9}{15}) = 3 - \frac{5}{15} = 3 - \frac{1}{3} = 2\frac{3}{3} - \frac{1}{3} = 2\frac{2}{3}
10) 8\frac{6}{23}-3 = (8 - 3) + \frac{6}{23} = 5 + \frac{6}{23} = 5\frac{6}{23}
11) 6-1\frac{5}{7} = (6 - 1) - \frac{5}{7} = 5 - \frac{5}{7} = 4\frac{7}{7} - \frac{5}{7} = 4\frac{2}{7}
12) 1\frac{13}{15}-1\frac{2}{15} = (1 - 1) + (\frac{13}{15} - \frac{2}{15}) = 0 + \frac{11}{15} = \frac{11}{15}
13) 28\frac{7}{20}-7 = (28 - 7) + \frac{7}{20} = 21 + \frac{7}{20} = 21\frac{7}{20}
14) 8\frac{2}{44}-1\frac{7}{44} = (8 - 1) + (\frac{2}{44} - \frac{7}{44}) = 7 - \frac{5}{44} = 6\frac{44}{44} - \frac{5}{44} = 6\frac{39}{44}
15) 18\frac{2}{14}-13\frac{7}{14} = (18 - 13) + (\frac{2}{14} - \frac{7}{14}) = 5 - \frac{5}{14} = 4\frac{14}{14} - \frac{5}{14} = 4\frac{9}{14}
Ответ: 1) 61\frac{4}{5}; 2) 48\frac{6}{17}; 3) 163\frac{13}{41}; 4) 67\frac{3}{4}; 5) 9\frac{11}{13}; 6) 434\frac{9}{13}; 7) 10\frac{1}{10}; 8) 3\frac{13}{49}; 9) 2\frac{2}{3}; 10) 5\frac{6}{23}; 11) 4\frac{2}{7}; 12) \frac{11}{15}; 13) 21\frac{7}{20}; 14) 6\frac{39}{44}; 15) 4\frac{9}{14}
У тебя отлично получается! Не останавливайся на достигнутом, и все получится!
