Answer 1

$1)3 \frac{3}{11} *1 \frac{2}{9} = \frac{36}{11}* \frac{11}{9} =4$
$2)4-2 \frac{3}{8} =1 \frac{5}{8}$
$3)1 \frac{5}{8} * \frac{16}{39} = \frac{13}{8} * \frac{16}{39} = \frac{2}{3}$
===========================
$1)4 \frac{2}{3} * \frac{9}{56} = \frac{14}{3} * \frac{9}{56} = \frac{3}{4}$
$2) \frac{3}{4} + \frac{9}{16} = \frac{12+9}{16} = \frac{21}{16}$
$3) \frac{21}{16} *1 \frac{1}{7} = \frac{21}{16} * \frac{8}{7} = \frac{3}{2} =1 \frac{1}{2}$
=====================
$\frac{5}{12} *2 \frac{3}{7} + \frac{5}{12} *3 \frac{4}{7} = \frac{5}{12} *(2 \frac{3}{7} +3 \frac{4}{7} )= \frac{5}{12} *6= \frac{5}{2} =2 \frac{1}{2}$
=====================
$1)6 \frac{1}{7} -5 \frac{3}{4} =6 \frac{4}{28} -5 \frac{21}{28} = \frac{11}{28}$
$2) \frac{11}{28} : \frac{11}{14} = \frac{11}{28}* \frac{14}{11} = \frac{1}{2}$
$3)3 \frac{3}{4} -1 \frac{5}{6} =3 \frac{9}{12} -1 \frac{10}{12} =1 \frac{11}{12}$
$4)1 \frac{11}{12} : \frac{1}{6} = \frac{23}{12} * \frac{6}{1} = \frac{23}{2} =11 \frac{1}{2}$
$5) \frac{1}{2} +11 \frac{1}{2} =12$
=====================
$1)5 \frac{4}{19} *3 \frac{4}{7} = \frac{99}{19} * \frac{25}{7} = \frac{2475}{133}$
$2)1 \frac{15}{19} : \frac{7}{25} = \frac{34}{19} * \frac{25}{7} = \frac{850}{133}$
$3) \frac{2475}{133} + \frac{850}{133} = \frac{3325}{133}=25$
$4)25-1 \frac{2}{3} =23 \frac{1}{3}$
=====================
$1)2 \frac{1}{7} :4 \frac{1}{6} = \frac{15}{7} * \frac{6}{25} = \frac{18}{35}$
$2) \frac{18}{35} *2 \frac{1}{3} = \frac{18}{35} * \frac{7}{3} = \frac{6}{5} =1 \frac{1}{5}$
======================
$1)7 \frac{1}{3} +2 \frac{1}{4} =7 \frac{4}{12} +2 \frac{3}{12} =9 \frac{7}{12}$
$2)9 \frac{7}{12} : \frac{1}{4} = \frac{115}{12} * \frac{4}{1} = \frac{115}{3} =38 \frac{1}{3}$
$3)38 \frac{1}{3} -30 \frac{5}{6} =38 \frac{2}{6} -30 \frac{5}{6} =7 \frac{3}{6} =7 \frac{1}{2}$
