1.  \frac{1}{2} + 4  \frac{2}{4} =  \frac{1}{2} +  \frac{18}{4} =  \frac{20}{4} = 5
2.  \frac{2}{3} + 5 \frac{1}{6} = \frac{2}{3} +  \frac{31}{6} =  \frac{35}{6} = 5 \frac{5}{6}
3.  \frac{1}{6} + 6 \frac{2}{3} =  \frac{1}{6} +  \frac{20}{3} =  \frac{41}{6} = 6 \frac{5}{6}
4.  \frac{2}{5} +  \frac{1}{10} =  \frac{5}{10} =  \frac{1}{2}
5. 2 \frac{6}{12} + 5 \frac{3}{7} =  \frac{30}{12} +  \frac{38}{7} =  \frac{420}{84} = 5 \frac{6}{14} = 5 \frac{3}{7}

menurut saya bgnii.. maaf kalau salah :)
5. 2[tex] \frac{6}{12} [/tex] + 5[tex] \frac{3}{7} [/tex] = [tex] \frac{30}{12} [/tex] + [tex] \frac{38}{7} [/tex] = [tex] \frac{456}{84} [/tex] = 5[tex] \frac{6}{14} [/tex] = 5[tex] \frac{3}{7} [/tex]
2 6/12 + 5 3/7 = 30/12 + 38/7 = 456/84 = 5 6/14 = 5 3/7
mksd saya yang nomor 5 gni

1.1/2+18/4=2/4+18/4=20/4=5
2.2/3+31/6=4/6+31/6=35/6=5 5/6
3.1/6+20/3=1/6+40/6==41/6=6 5/6
4.2/5+31/10=4/10+31/10=35/10=7/2=3 1/2
5.30/12+38/7=210/84+450/84=666/84=333/41
