Answer 1

1)
$frac{1}{5} + frac{1}{9} + frac{1}{3} = frac{9+5+15}{45} = frac{29}{45}$
2)
$frac{1}{2} + frac{3}{5} + frac{2}{3} = frac{15+18+20}{30} = frac{53}{30} =1 frac{23}{30}$
3)
$frac{5}{6} + frac{3}{8} + frac{1}{4} = frac{20+9+6}{24} = frac{35}{24} =1 frac{11}{24}$
4)
$frac{5}{9} + frac{1}{6} + frac{3}{4} = frac{20+6+27}{36} = frac{53}{36} =1 frac{17}{36}$
5)
$frac{1}{3} + frac{4}{9} + frac{5}{6} = frac{6+8+15}{18} = frac{29}{18} =1 frac{11}{18}$
6)
$frac{1}{4} + frac{1}{5}+ frac{3}{10} = frac{5+4+6}{20} = frac{15}{20} = frac{3}{4}$
