Question

calcule e simplifique o resultado se possivel:a]1/3+2/9+4/3 b]1/10+7/10+3/10 c]7/15+3/15-1/10 d]7/8-2/8-1/8

Answer 1

$a) \frac{1}{3} + \frac{2}{9} + \frac{4}{3} = \frac{17}{9} \\ \\ \\ b) \frac{1}{10} + \frac{7}{10} + \frac{3}{10} = \frac{11}{10} \\ \\ \\ c) \frac{7}{15} + \frac{3}{15} - \frac{1}{10} = \frac{17}{30} \\ \\ \\ \\ d) \frac{7}{8} - \frac{2}{8} - \frac{1}{8} = \frac{4}{8} = \frac{1}{2}$
