Multiply Decimal Numbers using the Partial Products Algorithm 5-106

Multiply left-to-right, using the partial products algorithm. Keep track of place values by aligning the decimal points and emphasizing each digit's correct place value. What's 2 x .8? Since 2 x 8/10 = 16/10 = 1 6/10 = 1.6, write 6 in the tenths place and 1 in the ones place. Add partial products vertically to get the total product.
