Answer 1

1. 1)
$2 frac{4}{9} + x = 3 frac{7}{9} \ x = 3 frac{7}{9} - 2 frac{4}{9 } \ x = 1 frac{3}{9}$
1. 2)
$3 frac{5}{7} - x = 1 frac{1}{7} \ x = 1 frac{1}{7} + 3 frac{5}{7} \ x = 4 frac{6}{7}$
2. 1)
$2 frac{3}{11} + 1 frac{5}{11} - 2 frac{5}{11} = frac{24}{11} + frac{16}{11} - frac{26}{11} = frac{14}{11} = 1 frac{3}{11}$
2. 2)
$5 frac{5}{8} - 3 frac{3}{8} + 2 frac{7}{8} = 5 frac{1}{8}$

2. 3)
$4 frac{8}{15} - 1 frac{6}{15} - 2 frac{1}{15 } = 1 frac{1}{15}$
3. 1)
$12 frac{1}{3} - (3 frac{1}{9} + 4 frac{2}{9} ) = 12 frac{1}{3} - 7 frac{1}{3} = 5$
3. 2)
$5 frac{1}{8} + 9 frac{3}{8} - 7 frac{5}{8} = 6 frac{7}{8}$
3. 3)
$6 frac{4}{11} - 2 frac{6}{11} + (4 frac{5}{11} - frac{1}{11} ) = 3 frac{9}{11} + 4 frac{4}{11} = 8 frac{2}{11}$
