Answer 1

1) 21 4/15 + 1 5/6 = 21 8/30 + 1 25/30 = 22 33/30

2) 22 33/30 - 9 7/30 = 13 26/30

3) 13 26/30 + 16 7/24 = ( 13 + 16 ) + ( 26/30 + 7/24 ) = 29 + 13/15 + 7/24 = 29 + 104+35/120 = 29 + 139/120 = 29 + 1 19/120 = 30 19/120

Answer 2

Ответ:

$21 \frac{4}{15} + 1 \frac{5}{6} - 9 \frac{7}{30} + 16 \frac{7}{24} = 21 \frac{4}{15} - 9 \frac{7}{30} = 21 \frac{16}{60} - 9 \frac{14}{60} = 12 \frac{2}{60} \\ 1 \frac{5}{6} + 16 \frac{7}{24} = 1 \frac{20}{24} + 16 \frac{7}{24} = 18 \frac{3}{24} \\ 12 \frac{2}{60} + 18 \frac{3}{24} = 12 \frac{4}{120} + 18 \frac{15}{120} = 30 \frac{19}{120}$
