Answer 1

Respuesta:

1.

a)

$\frac{19}{5}$

b)

$\frac{2}{3} + \frac{6}{5} = \frac{10}{15} + \frac{18}{15} = \frac{28}{15}$

c)

$\frac{3}{5} + \frac{4}{7} - \frac{6}{8} = \frac{168}{280} + \frac{160}{280} - \frac{210}{280} = \frac{118}{280}$

d)

$\frac{8}{15} - \frac{6}{17} = \frac{136}{255} - \frac{90}{255} = \frac{46}{255}$

2.

a)

$\frac{30}{99}$

b)

$\frac{160}{432}$
