é fácil!!!!. Mate. Matica

Answer 1

Resposta e Explicação passo a passo:

$1.a) \frac{5}{6}-\frac{1}{6}=\frac{5-1}{6}=\frac{4}{6}=\frac{2}{3}\\\\1.b) \frac{10}{25}-\frac{3}{25}=\frac{10-3}{25}=\frac{7}{25}\\\\1.c) \frac{7}{9}-\frac{2}{9}=\frac{7-2}{9}=\frac{5}{9}\\\\1.d) \frac{8}{5}-\frac{3}{5}=\frac{8-3}{5}=\frac{5}{5}=1\\\\1.e)\frac{13}{17}-\frac{11}{17}=\frac{13-11}{17}=\frac{2}{17}\\\\1.f)\frac{10}{19}-\frac{9}{19}=\frac{10-9}{19}=\frac{1}{19}$

$2.a)\frac{3}{4}-\frac{1}{6}=\frac{9}{12}-\frac{2}{12}=\frac{9-2}{12}=\frac{7}{12}\\\\2.b)\frac{1}{2}-\frac{1}{15}=\frac{15}{30}-\frac{2}{30}=\frac{15-2}{30}=\frac{13}{30}\\\\2.c)\frac{7}{8}-\frac{4}{9}=\frac{63}{72}-\frac{32}{72}=\frac{31}{72}\\\\2.d)\frac{5}{6}-\frac{3}{10}=\frac{25}{30}-\frac{9}{30}=\frac{16}{30}=\frac{8}{15}$

espero ter ajudado =)
