a. If a decimal is to be multiplied by a number that is a multiple of ten (10, 100,

1000, and so forth), move the decimal point as many places to the RIGHT as there are

zeros in the multiplier.

b. For example: When multiplying 0.2 times 100, move the decimal point one

place to the RIGHT for each of the zeros in the multiplier. There are two zeros,

therefore the decimal must be moved two places to the right.

Examples:

(1)

0.6 x 10 =

6

(4)

6.75 x 10

=

67.5

(2)

0.6 x 100 =

60

(5)

6.75 x 100

=

675

(3)

0.6 x 1000 =

600

(6)

6.75 x 1000

= 6750
