Answer 2

Resposta:

$a)\frac{1}{2} +\frac{3}{2} =\frac{4}{2}=2\\\\b) \frac{4}{3}+ \frac{5}{3}=\frac{9}{3} =3\\\\c)\frac{5}{6} +\frac{2}{6} = \frac{7}{6} =1\frac{1}{6}\\\\d)\frac{1}{2} +\frac{1}{3} =\frac{3+2}{6} =\frac{5}{6}$

$e)\frac{1}{2} +\frac{1}{4} =\frac{2+1}{4}=\frac{3}{4} =0,75 \\\\f)\frac{1}{3}+ \frac{1}{4} =\frac{4+3}{12}=\frac{7}{12} \\\\g)\frac{3}{4} -\frac{2}{3} =\frac{9-8}{12}=\frac{1}{12} \\\\h)\frac{2}{5} -\frac{1}{3} =\frac{6-5}{15} =\frac{1}{15}$

$i)\frac{6}{4} -\frac{1}{7} +\frac{1}{2} =\frac{42-4+14}{28}=\frac{38+14}{28}=\frac{52}{28}=\frac{13}{7}=1\frac{6}{7} \\\\j)\frac{2}{9} +\frac{1}{8} -\frac{1}{6} =\frac{16+9-12}{72}=\frac{25-12}{72}=\frac{13}{72} \\\\k)\frac{1}{2} +3=0,5+3=3,5$
