Answer 1

А)2 3/14+1 13/14=31/14+27/14=58/14=4 2/14= 4 1/7
Б)5 9/16+3 11/16=89/16+59/16=148/16=9 1/4
В)4 7/8+1=5 7/8

Answer 2

1)
$2 frac{3}{14} + 1 frac{13}{14} = 3 frac{16}{14} = 4 frac{2}{14} = 4 frac{1}{7}$

2 ) 
   $5 frac{9}{16} +3 frac{11}{16} =8 frac{20}{16} = 9 frac{4}{16} = 9 frac{1}{4}$

3) $4 frac{7}{8} +1 = 5 frac{7}{8}$
