Question

03. Efetue as operações e simplifique o resultado quando possível: a) 3/4 - 1/4 = e) 8/6 - 5/6 = b) 9/3 - 7/3 = f) 5/2 - 3/2 = c) 6/10 - 4/10 = g) 7/12 - 5/12 = d) 4/15 - 3/15 = h) 8/9 - 1/9 =

Answer 1

Resposta:

$a) \: \frac{3}{4} - \frac{1}{4} = \frac{2}{4} = \frac{1}{2} \\ \\ e) \frac{8}{6} - \frac{5}{6} = \frac{3}{6} = \frac{1}{2} \\ \\ b) \frac{9}{3} - \frac{7}{3} = \frac{2}{3} \\ \\ f) \frac{5}{2} - \frac{3}{2} = \frac{2}{2} = 1 \\ \\ c) \frac{6}{10} - \frac{4}{10} = \frac{2}{10} = \frac{1}{5} \\ \\ g) \frac{7}{12} - \frac{5}{12} = \frac{2}{12} = \frac{1}{6} \\ \\ d) \frac{4}{15} - \frac{3}{15} = \frac{1}{15} \\ \\ h) \frac{8}{9} - \frac{1}{9} = \frac{7}{9}$
