b)0,23. g) 3,076

c)1,2. h)58,01

d)0,00045. i)0,0006

e)0,56. j) 2,004

Answer 1

0,3 3/10 0,23 23/10 12/10 45/10000 d   e 56/10   f 56,89 5689/100  g 3076/1000  h 58/10 i 6/10000 j 2004/1000

Answer 2

a)0,3= 3/10
b)0,23= 23/100
c)1,2= 12/10 = (12/2)/(10/2)= 6/5 
d)0,00045 = 45/100000 = (45/5)/(100000/5)= 9/20000
e)0,56 =  56/100 = (56/4)/(100/4)= 14/25
f)56,89= 5689/100
g) 3,076= 3076/1000 = (3076/4 )/(1000/4 )= 769/ 250
h)58,01= 5801/100
 i)0,0006 = 6/10000 = (6/2)/(10000/2) = 3/5000
j) 2,004 = 2004/1000 = (2004/2)/(1000/2)=  501/250
