$frac{3}{8}+frac{1}{2}=frac{3}{8}+frac{4}{8}=frac{3+4}{8}=frac{7}{8}\\frac{3}{8}+frac{1}{6}=frac{9+4}{24}=frac{13}{24}\\frac{3}{8}+frac{3}{7}=frac{21+24}{56}=frac{45}{56}\\frac{3}{8}+frac{3}{16}=frac{6+3}{16}=frac{9}{16}\\frac{3}{8}+1frac{1}{4}=frac{3+10}{8}=frac{13}{8}\\frac{3}{8}+2frac{5}{8}=frac{3+21}{8}=3\\frac{3}{8}+frac{7}{12}=frac{9+14}{24}=frac{23}{24}\\frac{3}{8}+frac{3}{4}=frac{3+6}{8}=frac{9}{8}$

$frac{3}{8}+frac{5}{24}=frac{9+5}{24}=frac{14}{24}=frac{7}{12}\\frac{3}{8}+frac{5}{6}=frac{9+20}{24}=frac{29}{24}=1frac{5}{24} \\frac{3}{8}+frac{7}{8}=frac{3+7}{8}=frac{10}{8}=1frac{2}{8}=1frac{1}{4}\\frac{3}{8}+1frac{1}{4}=frac{3+10}{8} =frac{13}{8}=1frac{5}{8}\\frac{3}{8}+frac{13}{32}=frac{12+13}{32}=frac{25}{32}\\frac{3}{8}+1frac{7}{16}=frac{6+23}{16}=frac{29}{16}=1frac{13}{16}\\frac{3}{8}+frac{11}{72}=frac{27+11}{72}=frac{38}{72}=frac{19}{36}$
