We'll change the decimal 0.04 to a fraction,
4/100.
We'll move the decimal point in 0.04, 2 places to
the right and we'll transform the decimal number into a whole number, also, we'll move
the decimal point in denominator, the same number of
places:
0.04/1.0 = 0.4/10.0 =
4.0/100.0
Now, we'll divide both, numerator and
denominator, by 4:
4/100 =
1/25
Now, we'll divide the ratio1/25 by
5:
(1/25)/5 = 1/25*5 =
1/125
Now, we'll divide
1:125
1 : 125 =
0.008
10
100
1000
The
result of division:
0.04 : 5 =
0.008
We also can calculate in
this way:
0.04 :
5
We'll move the decimal point in the dividend (0.04) 2
places to the right:
4 :
500
We'll write to the right the result of division of 4
and 500:
4:500 = 0
We'll place
the decimal point after 0 result and we'll divide 40 by
500:
40 : 500 = 0.0
400: 500 =
0.00
4000:500 =
0.008
