Question

simplificado, porfa *me urge*

Answer 1

Respuesta:

1)  $\frac{2}{5} + \frac{3}{7} = \frac{15}{35} + \frac{14}{35} = \frac{29}{35}$

2) $\frac{4}{9} + \frac{11}{3} =\frac{99}{27} + \frac{12}{27} = \frac{111}{27} = 4\frac{1}{9}$

3) $\frac{7}{2} - \frac{1}{5} = \frac{35}{10} -\frac{2}{10} = \frac{33}{10} =3\frac{3}{10}$

4)  $\frac{6}{5} - \frac{2}{3} = \frac{18}{15} -\frac{10}{15} =\frac{8}{15}$

5) $2\frac{1}{4} + 1\frac{1}{3} = \frac{9}{4} +\frac{4}{3} =\frac{27}{12}+ \frac{16}{12} = \frac{43}{12} = 3\frac{7}{12}$

6) $3\frac{1}{2} - 2\frac{2}{3} = \frac{7}{2}-\frac{8}{3} =\frac{21}{6} - \frac{16}{6} =\frac{5}{6}$

Answer 2

$\frac{2}{5}+\frac{3}{7}=\frac{14+15}{35}=\frac{29}{35}$

$\frac{4}{9}+\frac{11}{3}=\frac{12+99}{27}=\frac{111}{27}=4\frac{3}{27}$

$\frac{7}{2}-\frac{1}{5}=\frac{35-2}{10}=\frac{33}{10}=3\frac{3}{10}$

$\frac{6}{5}-\frac{2}{3}=\frac{18-10}{15}=\frac{8}{15}$

$2\frac{1}{4}+1\frac{1}{3}=\frac{9}{4}+\frac{4}{3}=\frac{27+16}{12}=\frac{43}{12}=3\frac{7}{12}$

$3\frac{1}{2}-1\frac{2}{3}=\frac{7}{2}-\frac{8}{3}=\frac{21-16}{6}=\frac{5}{6}$

espero que te ayude :)
