Multiplying Decimals

A decimal is a fraction whose denominator is a power of ten, represented with a dot (decimal point) to separate the whole number from the fractional part.

To multiply decimals, multiply the numbers as if they were whole numbers, then count the total number of decimal places in both numbers and place the decimal point in the product accordingly.

The decimal point is a dot used to separate the whole number part from the fractional part in a decimal number.

0.15 has 2 decimal places.

0.6 has 1 decimal place.

0.15 x 0.6 = 0.09.

2.39 x 4.37 = 10.4443.

Count the total number of decimal places in the factors and place the decimal point in the product accordingly.

The product will have 5 decimal places.
