Answer 1

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

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

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

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

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

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