Answer 2

Ответ:

10.1) 48,93 + 41,83 = 90,76

48,93 - 41,83 = 7,10

10.2) 100,99 + 99,01 = 200

100,99 - 99,01 = 1,98

10.3) 568,19 + 2,81 = 571

568,19 - 2,81 = 565,38

10.4) 40,007 + 39,07 = 79,077

40,007 - 39,07 = 0,937

$11.1) 7\frac{11}{12} + 4\frac{9}{16} = 11 \frac{11}{12} + \frac{9}{16} = 11 \frac{33+36}{48} = 11\frac{69}{48} = 12\frac{21}{48} = 12\frac{7}{16}\\\\7\frac{11}{12} - 4\frac{9}{16} = 3 \frac{11}{12} - \frac{9}{16} = 3 \frac{33-36}{48} = 3\frac{-3}{48} = 3\frac{-1}{16} = 2\frac{15}{16}$

$11.2) 5\frac{7}{30} + 3\frac{11}{18} = 8 \frac{7}{30} + \frac{11}{18} = 8 \frac{21+55}{90} = 8\frac{76}{90} = 8\frac{38}{45}\\\\5\frac{7}{30} - 3\frac{11}{18} = 2 \frac{7}{30} - \frac{11}{18} = 2 \frac{21-55}{90} = 2\frac{-34}{90} = 1\frac{56}{90} = 1\frac{28}{45}$

$11.3) 25\frac{13}{42} + 19\frac{9}{14} = 44\frac{13}{42} + \frac{9}{14} = 44\frac{13+27}{42} = 44\frac{40}{42} = 44\frac{20}{21}\\\\25\frac{13}{42} - 19\frac{9}{14} = 6\frac{13}{42} - \frac{9}{14} = 6\frac{13-27}{42} = 6\frac{-14}{42} = 6\frac{-1}{3} = 5\frac{2}{3}$

$11.4) 49\frac{3}{20} + 38\frac{1}{12} = 87\frac{3}{20} + \frac{1}{12} = 87\frac{9+5}{60} = 87\frac{14}{60} = 87\frac{7}{30}\\\\49\frac{3}{20} - 38\frac{1}{12} = 11\frac{3}{20} - \frac{1}{12} = 11\frac{9-5}{60} = 11\frac{4}{60} = 11\frac{1}{15}$
