Answer 1

.a)
$+0,6= \frac{6}{10} = \frac{6:2}{10:2} = \frac{3}{5}$

b)
$-2,5=- \frac{25}{10} =- \frac{25:5}{10:5} =- \frac{5}{2}$

c)
$-0,75=- \frac{75}{100} =- \frac{75:25}{100:25} =- \frac{3}{4}$

d)
$+1,6=+ \frac{16}{10} = \frac{16:2}{10:2} =+ \frac{8}{5}$

e)
$0,02= \frac{2}{100} = \frac{2:2}{100:2} = \frac{1}{50}$

f)
$-4,5=- \frac{45}{10} =- \frac{45:5}{10:5} =- \frac{9}{2}$
