17 1 1
_ - _ + _ = ?
15 5 6

Answer 1

$= \frac{5}{48} + \frac{18}{48} + \frac{1}{48} = \frac{24}{48} = \frac{1}{2}$
$= \frac{21}{20} - \frac{3}{8} - \frac{1}{5} = \frac{42}{40} - \frac{15}{40} - \frac{8}{40} = \frac{19}{40}$
$= \frac{17}{15} - \frac{1}{5} + \frac{1}{6} = \frac{34}{30} - \frac{6}{30} + \frac{5}{30} = \frac{33}{30} = \frac{11}{10} = 1 \frac{1}{10}$
