Question

determine as frações irredutíveis:
a) 0,16
b)0,08
c)0,081
d)4,5
e)1,002

Answer 1

a) 16/100=4/25
b) 8/100= 2/25
c) 81/1000= 0,81/10
d) 45/10 = 9/2
e) 1002/1000= 1,02/10

Answer 2

a) 0,16 = $\frac{16}{100}$ = $\frac{8}{50}$ = $\frac{4}{25}$

b) 0,08 = $\frac{8}{100}$ = $\frac{4}{50}$ = $\frac{2}{25}$

c) 0,081 = $\frac{81}{1000}$

d) 4,5 = $\frac{18}{4}$ = $\frac{9}{2}$
