1/7 + 2/3 =




2/5 + 1/2 - 3/6 =



1/4 + 1/2 - 3/2 + 5/10 =



7/5 - 1/8 =

Answer 1

Respuesta:

$a)\frac{1}{7} + \frac{2}{3} = \frac{3+ 14}{21} = \frac{17}{21}\\\\b)\frac{2}{5} + \frac{1}{2} - \frac{2}{6} = \frac{4+5}{10} - \frac{2}{6} = \frac{9}{10} - \frac{2}\\{6}= \frac{54-20}{60} = \frac{34}{60}\\\\c)\frac{1}{4} +\frac{1}{2} -\frac{3}{2} + \frac{5}{10} = \frac{2+4}{8} - \frac{3}{2} + \frac{5}{10} = \frac{6}{8} - \frac{3}{2} + \frac{5}{10} = \frac{12-24}{16} + \frac{5}{10} = \frac{36}{16} + \frac{5}{10} = \frac{360+86} {160}= \frac{446}{160}$

$d) \frac{7}{5} -\frac{1}{8} =\frac{5-56}{40} = \frac{-51}{40}$
