b. A whole number may be divided by a decimal by:
(1)
Making the divisor a whole number by moving the decimal point to the
right as many places as necessary.
(2)
Placing a decimal point after the whole number (dividend) and then
moving the decimal point the same number of places to the right as the decimal point in
the divisor was moved.
(3)
Divide in the usual manner.
EXAMPLE: 55 : 0.2
___
_____
____
0.2)55 = 0.2.)55.0. = 02)550.
Thus, 55 : 0.2 = 275
c.
Now to divide a decimal by a decimal, all we do is:
(1)
Make the divisor a whole number.
(2)
Move the decimal point in the dividend the same number of places as
the decimal in the divisor was moved.
(3)
Place the decimal point in the quotient directly above the decimal point
in the dividend.
(4)
Divide in the usual manner.
EXAMPLE: 5.25 : 2.5 =
______
2.5.)5.2.5 = 25)52.5 = 2.1
Thus 5.25 : 2.5 = 2.1
d. If a decimal is to be divided by a multiple of ten (10, 100, 1000, etc.), move
the decimal point as many places to the left as there are zeroes in the divisor.
