Answer 1

$4 frac{13}{17} + 5 frac{4}{17} = 9 frac{17}{17} = 10$

$3 frac{8}{11} + 2 frac{6}{11} = 5 frac{14}{11} = 6 frac{3}{11}$

$1 - frac{16}{21 } = frac{21}{21} - frac{16}{21} = frac{5}{21}$

$5 - 2 frac{3}{8} = 4 frac{8}{8} - 2 frac{3}{8} = 2 frac{5}{8}$

$8 frac{4}{9} - 3 frac{7}{9} = frac{76}{9} - frac{34}{9} = frac{42}{3} = 14$

$12 frac{19}{44} - 6 frac{37}{44} = frac{547}{44} - frac{301}{44} = frac{123}{22} = 5 frac{13}{22}$
