b) $\frac{32}{25}$
c) $\frac{25}{8}$
d) $\frac{-125}{4}$

Answer 2

Oie, Td Bom?!

a)

$0,57 = \frac{57}{100}$

b)

$1,28 = \frac{128}{100} = \frac{128 \div 4}{100 \div 4} = \frac{32}{25}$

c)

$3,125 = \frac{3125}{1000} = \frac{3125 \div 125}{1000 \div 125} = \frac{25}{8}$

d)

$- 31,25 = - \frac{3125}{100} = - \frac{3125 \div 25}{100 \div 25} = - \frac{125}{4}$
