Answer 1

Răspuns:

1. a)

$\frac{3}{5} + \frac{3}{5} = \frac{6}{5}$

b)

$\frac{2}{5} + \frac{2}{5} + \frac{2}{5} = \frac{6}{5}$

c)

$\frac{2}{5} + \frac{2}{5} + \frac{2}{5} + \frac{2}{5} + \frac{2}{5} + \frac{2}{5} + \frac{2}{5} = \frac{14}{5}$

d)

$\frac{7}{5} + \frac{7}{5} = \frac{14}{5}$

e)

$\frac{3}{4} + \frac{3}{4} + \frac{3}{4} + \frac{3}{4} + \frac{3}{4} + \frac{3}{4} = \frac{18}{4}$

f)

$\frac{3}{2} + \frac{3}{2} + \frac{3}{2} = \frac{9}{2}$

g)

$\frac{7}{25} + \frac{7}{25} + \frac{7}{25} + \frac{7}{25} + \frac{7}{25} + \frac{7}{25} + \frac{7}{25} + \frac{7}{25} + \frac{7}{25} + \frac{7}{25} + \frac{7}{25} + \frac{7}{25} + \frac{7}{25} + \frac{7}{25} + \frac{7}{25} + \frac{7}{25} + \frac{7}{25} + \frac{7}{25} + \frac{7}{25} + \frac{7}{25} = \frac{140}{25}$

h)

$\frac{1}{36} + \frac{1}{36} + \frac{1}{36} + \frac{1}{36} + \frac{1}{36} + \frac{1}{36} + \frac{1}{36} + \frac{1}{36} + \frac{1}{36} + \frac{1}{36} + \frac{1}{36} + \frac{1}{36} + \frac{1}{36} + \frac{1}{36} + \frac{1}{36} + \frac{1}{36} + \frac{1}{36} + \frac{1}{36} + \frac{1}{36} + \frac{1}{36} + \frac{1}{36} = \frac{21}{36}$
