Explicación paso a paso:

Operaciones con fracciones

1.

[tex]\frac{2}{5} + \frac{1}{3}=\frac{(2)(3) + (1)(5) }{15} =\frac{6+5}{15} =\frac{11}{15}[/tex]

2.

[tex]\frac{5}{2} - \frac{2}{3}=\frac{(5)(3) - (2)(2) }{6} =\frac{15-4}{6} =\frac{11}{6}[/tex]

3.

[tex]\frac{3}{4} + \frac{4}{5}+ \frac{7}{8}=\frac{(3)(10) +(4)(8) +(7)(5) }{40} =\frac{30+32+35}{40} =\frac{97}{40}[/tex]

4.

[tex]\frac{3}{5}\times \frac{2}{3}=\frac{3 \times 2}{5 \times 3}=\frac{6}{15} =\frac{2}{5}[/tex]

5.

[tex]\frac{3}{4}\div \frac{5}{7} = \frac{3}{4}\times \frac{7}{5} = \frac{3 \times 7}{4 \times 5} = \frac{21}{20}[/tex]

6.

[tex]3\frac{1}{4} \div \frac{2}{3} = \frac{13}{4}\div \frac{2}{3} = \frac{13}{4}\times \frac{3}{2} = \frac{13 \times 3}{4 \times 2} = \frac{39}{8}[/tex]
