Answer 1

Diez ejemplos de resta de números racionales:

$1) \frac{3}{4} - \frac{2}{4} = \frac{3-2}{4} = \frac{1}{4}$

$2) \frac{3}{5} - \frac{1}{10}= \frac{10:5.3 - 10 : 10 . 1}{10} = \frac{6-1}{10} = \frac{5}{10} = \frac{1}{2}$

$3) \frac{17}{21} - \frac{2}{21} = \frac{17-2}{21} = \frac{15}{21} = \frac{5}{7}$

$4) \frac{4}{2} - \frac{7}{10} - \frac{1}{5} = \frac{10:2.4 - 10 : 10 .7 - 10 : 5 . 1}{10} = \frac{20-7-2}{10} = \frac{11}{10}$

$5) \frac{90}{7} - \frac{5}{7} = \frac{90-5}{7} = \frac{85}{7}$

$6) \frac{30}{7} - \frac{3}{5} = \frac{35:7.30 - 35 : 5 . 3 }{35} = \frac{150-21}{35} = \frac{129}{35}$

$7) \frac{10}{6} - \frac{12}{6} - \frac{30}{6} = \frac{10-12-30}{6}= \frac{-32}{6} = \frac{-16}{3}$

$8) \frac{3}{9} - \frac{5}{2} = \frac{18:9.3 - 18 : 2 . 5}{18} = \frac{6-45}{18} = \frac{-39}{18} = \frac{-13}{6}$

$9) \frac{48}{8} - \frac{40}{8} = \frac{48-40}{8} = \frac{8}{8} = \frac{1}{1} = 1$

$10) \frac{300}{100} - \frac{2}{10} = \frac{100:100.300 - 100:10 . 2}{100} = \frac{300-20}{100} = \frac{280}{100} = \frac{28}{10} = \frac{14}{5}$
