♣Multiplying Decimals♣

Multiply the numbers just as if they were whole numbers:

Step#1 Line up the numbers on the right--do not align the decimal points.

Step#2 Starting on the right, multiply each digit in the top number by each digit in the bottom number, just as with whole numbers

Step#3 Add the products. Place the decimal point in the answer by starting at the right and moving the point the number of places equal to the sum of the decimal places in both numbers multiplied.

Example 37.7 x 2.8 = ? --->       37.7     ( 1 decimal place )    x  2.8     ( 1 decimal place )   3016 +754   105.56       ( 2 decimal places, move point 2 places left )
