Questão 1

$a \frac{2}{7} + \frac{5}{7} = \frac{7}{7}$

$b \: \frac{13}{20} - \frac{6}{20 } = \frac{8}{20}$

$c \: \frac{8}{9} - \frac{1}{9} = \frac{7}{9}$

$d \frac{2}{10| } + \frac{3}{10} + \frac{4}{10} = \frac{9}{10}$

$e \: \frac{6}{15} + \frac{1}{15} + \frac{10}{15} = \frac{17}{15}$

$f \: \frac{57}{100} - \frac{43}{100} = \frac{14}{100| }$
