a) 15 5/6 + 1 1/6 = 17
b) 5 5/12 + 9 1/12 = 14 6/12
c) 12 7/15 + 12 13/15 = 25 5/15
d) 23 13/20 + 31 17/20 = 55 10/20
[tex]15 \frac{5}{6} + 1 \frac{1}{6} = 16 \frac{6}{6} = 17[/tex]
[tex]5 \frac{5}{12} + 9 \frac{1}{12} = 14 \frac{6}{12} = 14 \frac{1}{2} [/tex]
[tex]12 \frac{7}{15} + 12 \frac{13}{15} = 24 \frac{20}{15} = 25 \frac{5}{15} = 25 \frac{1}{3} [/tex]
[tex]23 \frac{13}{20} + 31 \frac{17}{20} = 54 \frac{30}{20} = 55 \frac{10}{20} = 55 \frac{1}{2} [/tex]
