Question

resuelve las siguientes operaciones con números racionales

a) 3/5 - 2 2/5 =
b) -3 2/3 + 2 1/9 - 1/3 =
c) -2/7 + 2 1/14 =
d) -7/11 + 3/22 + 1 1/22
e) -1/4 + 1 3/5
f) -1 2/3 + 3 5/6 - 3/2​

Answer 1

$\frac{3}{5} - 2\frac{2}{5}\\\\\frac{3}{4} -\frac{12}{5}\\\\\frac{15 - 48}{20} \\\\\frac{-33}{20}$

$-3\frac{2}{3}+2\frac{1}{9} -\frac{1}{3}\\\\-\frac{11}{3} +\frac{19}{9}-\frac{1}{3}\\\\-\frac{33}{9} +\frac{19}{9}-\frac{3}{9}\\\\\frac{-33+19-3}{9}\\\\ -\frac{17}{3}$

$-\frac{2}{7} + 2\frac{1}{14}\\\\-\frac{2}{7} +\frac{29}{14}\\\\-\frac{4}{14} +`\frac{29}{14}\\\\\frac{-4+29}{14}\\\\ \frac{25}{14}$

$-\frac{7}{11} +\frac{3}{22} + \frac{11}{22}\\\\-\frac{14}{22} +\frac{3}{22} + \frac{11}{22}\\\\\frac{-14+3+11}{22}\\\\\frac{-14+14}{22}\\\\\frac{0}{24}\\\\0$

$-\frac{1}{4} +1\frac{3}{5}\\\\-\frac{1}{4} +\frac{8}{5} \\\\\frac{-5+32}{20} \\\\\frac{27}{20}$
