Answer 1

a)

$\frac{3}{5} = 0.6$

b)

$\frac{9}{25} = 0.36$

c)

$\frac{8}{48} = 0.16$

(Dízima periódica)

d)

$\frac{3}{2} + \frac{2}{8} \\ \frac{12 + 2}{8} \\ \frac{14 \div 2}{8 \div 2} \\ \frac{7}{4} = 1.75$

e)

$\frac{8}{5} - \frac{3}{6} \\ \frac{48 - 15}{30} \\ \frac{33 \div 3}{30 \div 3} \\ \frac{11}{10} = 1.1$

f)

$\frac{9}{112} + \frac{3}{8} - \frac{2}{10} \\ \frac{45 + 210 - 112}{560} \\ \frac{143}{560} = 0.2553571$
