Answer 2

c)1,28=128/100=32/25       d)-3,12=-312/100=78/25

Answer 3

a/ \(0,32=\frac{32}{100}=\frac{8}{25}\)

b/ \(-0,124=\frac{-124}{1000}=\frac{-31}{250}\)

c/ \(1,28=\frac{128}{100}=\frac{32}{25}\)

d/ \(-3,12=\frac{-312}{100}=\frac{-78}{25}\)

Answer 4

a) 0,32 = 32/100 = 8/25

b) -0,124 = -124/1000 = -31/25

c) 1,28 = 128/100 = 32/25

d) -3,12 = -312/100 = -78/25

Answer 5

a)\(0,32=\dfrac{32}{100}=\dfrac{8}{25}\)

b)\(-0,124=\dfrac{-124}{1000}=\dfrac{-31}{250}\)

c)\(1,28=\dfrac{128}{100}=\dfrac{32}{25}\)

d)\(-3,12=\dfrac{-312}{100}=\dfrac{-78}{25}\)
