(1) 12\frac{1}{2} -9\frac{1}{4}

Let us convert mixed fraction into improper fraction.

$12\frac{1}{2} -9\frac{1}{4}=\frac{25}{2} -\frac{37}{4}

Make the denominator same.

              $=\frac{25\times2}{2\times2} -\frac{37}{4}

              $=\frac{50}{4} -\frac{37}{4}

              $=\frac{13}{4}

Now convert improper into mixed fraction.

$12\frac{1}{2} -9\frac{1}{4}=3\frac{1}{4}

(2) 5\frac{3}{4}-2\frac{5}{12}

$5\frac{3}{4}-2\frac{5}{12}=\frac{23}{4}-\frac{29}{12}

Make the denominator same.

               $=\frac{23\times3}{4\times3}-\frac{29}{12}

               $=\frac{69}{12}-\frac{29}{12}

              $=\frac{40}{12}

$5\frac{3}{4}-2\frac{5}{12}=3\frac{4}{12}=3\frac{1}{3}

(3) 7\frac{1}{5}-3\frac{7}{10}

$7\frac{1}{5}-3\frac{7}{10}=\frac{36}{5}-\frac{37}{10}

Make the denominator same.

              $=\frac{36\times2}{5\times2}-\frac{37}{10}

              $=\frac{72}{10}-\frac{37}{10}

              $=\frac{35}{10}

$7\frac{1}{5}-3\frac{7}{10}=3\frac{5}{10}=3\frac{1}{2}

(4) 11\frac{2}{3}-8\frac{1}{2}

$11\frac{2}{3}-8\frac{1}{2}=\frac{35}{3}-\frac{17}{2}

               $=\frac{35\times2}{3\times2}-\frac{17\times3}{2\times3}

               $=\frac{70}{6}-\frac{51}{6}

               $=\frac{19}{6}

$11\frac{2}{3}-8\frac{1}{2}=3\frac{1}{6}
