Answer 1

Explicação passo-a-passo:

$a) \frac{1 - 20}{8} = \frac{ - 19}{8} = - \frac{19}{8} \\ b) \frac{24 - 7}{21} = \frac{17}{21} \\ c) \frac{25 - 10}{10} = \frac{11}{10} \\ d) \frac{7}{2} - \frac{1}{3} = \frac{21 - 2}{6} = \frac{19}{6}$

$a) \frac{21 + 108 + 8}{24} = \frac{137}{24} \\ b) \frac{7 + 20 + 140}{35} = \frac{167}{35} \\ c) \frac{315 + 56 + 20}{140} = \frac{391}{140} \\ d) \frac{35 + 12 + 252}{42} = \frac{299}{42}$

$a) \frac{21 - 108 - 8}{24} = \frac{ - 95}{24} = - \frac{ 95}{24} \\ b) \frac{7 - 20 - 140}{35} = \frac{ - 153}{35} = - \frac{153}{35} \\ c) \frac{63 - 8 - 168}{28} = \frac{ - 113}{28} = - \frac{113}{28} \\ d) \frac{35 - 12 - 252}{42} = - \frac{ - 229}{42} = - \frac{229}{42}$
