а) $3 - \frac{1}{4} = 2\frac{4}{4} - \frac{1}{4} = 2\frac{3}{4}$
б) $2 - \frac{1}{3} =$
в) $5 - \frac{3}{4} =$
г) $10 - \frac{2}{9} =$
д) $11 - \frac{11}{100} =$
е) $5 - \frac{2}{7} =$
ж) $13 - \frac{7}{10} =$
з) $1 - \frac{2}{5} =$

$3 - \frac{1}{4} = 2\frac{4}{4} - \frac{1}{4} = 2\frac{3}{4}$
$2 - \frac{1}{3} = 1\frac{3}{3} - \frac{1}{3} = 1\frac{2}{3}$
$5 - \frac{3}{4} = 4\frac{4}{4} - \frac{3}{4} = 4\frac{1}{4}$
$10 - \frac{2}{9} = 9\frac{9}{9} - \frac{2}{9} = 9\frac{7}{9}$
$11 - \frac{11}{100} = 10\frac{100}{100} - \frac{11}{100} = 10\frac{89}{100}$
$5 - \frac{2}{7} = 4\frac{7}{7} - \frac{2}{7} = 4\frac{5}{7}$
$13 - \frac{7}{10} = 12\frac{10}{10} - \frac{7}{10} = 12\frac{3}{10}$
$1 - \frac{2}{5} = \frac{5}{5} - \frac{2}{5} = \frac{3}{5}$
