Answer 1

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