EXAMPLE

Multiply 7.32 by 0.032.

Count off the 5 places

from right to left in the product.

Between this

figure and the next one

to the left, place the decimal point. You should

now have as many figures

to the right of the decimal point in the product as

the total number you had

in the two factors.

When a whole number or a decimal fraction is multiplied by 0.1, the decimal

point is simply moved one place to the left. If multiplying by 0.01, the

decimal point is moved two places to the left. The decimal point is moved

three places left when multiplying by 0.001.

If necessary, zeros may be

added to the left of the multiplicand (the number to be multiplied). Thus,

32.4 x 0.0001 provides a product of 0.00324.

However, when a decimal fraction is multiplied by 10, move the decimal point

one place to the right.

When multiplying by 100, 1000, etc., simply move

the decimal point to the right as many places as there are zeros in the

multiplier.

10.

Division

Move the decimal point in the divisor to the right of the right-hand figure.

Then move the decimal point in the dividend to the right, the same number of

places that the point was moved in the divisor (add zeros to the dividend if

necessary). Place the decimal point in the quotient directly above the new

position of the decimal point in the dividend. Divide as in whole numbers.

When dividing by 0.1, 0.01, 0.001, etc., move the decimal point one, two,

three, etc., places in the dividend to the right, adding zeros if needed.

Therefore, when dividing
