If the numbers X and Y have p and q digits after the decimal point each, then their product, X*Y will have p+q decimal places - before any trailing zeros are removed.
34.44 = 2 x 17.22 or 4 x 8.61, so the answer would appear to be two places.
Well, honey, any multiplication problem where both numbers have decimal places will give you a product with two decimal places. It's as simple as that. Just multiply those numbers together and you'll get your fancy little answer with two decimal spots. Math doesn't have to be a drag, darling, just embrace those decimals and get multiplying!
0.35 x 20 = 7 0.35 x 20 ------ 7.00 First, multiply 35 by 0, the product is---------0. Then, multiply 35 by 2, the product is------70. ============================ Putting 0 and 70 together, we get--------------700. 0.35 has two decimal places to the left so put the decimal place of 700 two places to the left too and we get 7.
To multiply two digit decimal numbers, multiply the numbers as you would without the decimals. To put the decimal in the answer, count the number of decimal places in the two numbers and put the decimal in the answer that many places to the left. For example: 5.12 x 6.35 = 32.5120. If the numbers were 51.2 x 63.5, the answer would be 3251.20.
If two decimal numbers have x and y digits after the decimal point respectively, then their product has (x + y) digits after the decimal point.
