Answer 1

2/51+ 1/9+3/17= 6/153+ 17/153+ 27/153= 50/153;
2/21+ 4/15+6/35= 10/105+ 28/105+ 18/105=56/105;
5/8+ 1/6+7/12= 15/24+4/24+14/24=33/24= 1 9/24= 1 3/8;
3/11+9/22+4/55=30/110+ 45/110+8/110=83/110;
1/24+11/30+5/12=5/120+ 44/120+ 50/120= 99/120=33/40.

Answer 2

$frac{2}{51}+ frac{1}{9} + frac{3}{17}= frac{6+17+27}{153} = frac{50}{153}$

$frac{2}{21}+ frac{4}{15}+ frac{6}{35}= frac{10+28+18}{105} = frac{56}{105}$

$frac{5}{8}+ frac{1}{6}+ frac{7}{12}= frac{15+4+14}{24} = frac{33}{24}$ = $1 frac{9}{24}$

$frac{3}{11}+ frac{9}{22}+ frac{4}{55}= frac{30+45+8}{110} = frac{83}{110}$

$frac{1}{24}+ frac{11}{30}+ frac{5}{12}= frac{5+44+50}{120} = frac{99}{120}$ = $frac{33}{40}$
