Answer 1

Ответ:

1)

$9 \frac{4}{5} - 3 \frac{3}{10} = (9 - 3) + ( \frac{4}{5} - \frac{3}{10} ) = 6 \frac{1}{2} = \frac{13}{2}$

$7 \frac{5}{12} - 6 \frac{1}{6} = (7 - 6) + ( \frac{5}{12} - \frac{1}{6} ) = 1 \frac{1}{4} = \frac{5}{4}$

$25 \frac{3}{11} - 4 \frac{5}{22} = (25 - 4) + ( \frac{3}{10} - \frac{5}{22} = 21 \frac{1}{22} = \frac{463}{22}$

2)

$8 \frac{5}{6} - 8 \frac{7}{12} = (8 - 8) + ( \frac{5}{6} - \frac{7}{12}) = \frac{1}{4}$

$27 \frac{9}{10} - 17 \frac{4}{15} = (27 - 17) + ( \frac{9}{10} - \frac{4}{15} ) = 10 \frac{19}{30} = \frac{319}{30}$

$15 \frac{23}{24} - 10 \frac{7}{12} = (15 - 10) + ( \frac{23}{24} - \frac{7}{12} ) = 5 \frac{3}{8} = \frac{43}{8}$

3)

$17 \frac{6}{7 } - 13 \frac{1}{21} = (17 - 13) + ( \frac{6}{7} - \frac{1}{21} ) = 4 \frac{17}{21} = \frac{101}{21}$

$11 \frac{2}{3} - 7 \frac{1}{6} = (11 - 7) + ( \frac{2}{3} - \frac{1}{6} ) = 4 \frac{1}{2} = \frac{9}{2}$

$9 \frac{5}{8} - 9 \frac{5}{12} = (9 - 9) + ( \frac{5}{8} - \frac{5}{12} ) = \frac{5}{24}$
