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.
There are: 3.012 times 6.2034 = 18.6846408 which makes 7 decimal places
Generally speaking, with the exception of trailing zeroes, the number of decimal places in the answer of a multiplication sum is equal to the sum of the number of decimal places in the question. Therefore, 4.97 x 3.456 contains five decimal places in total, therefore the answer contains five decimal places. In this instance, 4.97 x 3.456 = 17.17632.
If the two numbers have x and y decimal places respectively, then the raw product (before deleting and trailing 0s) has (x + y) digits after the decimal point.
The product of 0.02x 0.02 is 0.0004,and the product of 0.2 x 0.002 is also 0.0004, so they are the same. In each case, the answer requires 4 decimal places. In the first problem, you have two figures with two decimal places each, equaling four decimal places. In the second problem, you have a figure with one decimal place and a figure with three decimal places, also equaling four decimal places.
This is not necessarily true. 2 x 0.55 = 1.1
Count up the number of decimals in BOTH multiples. The decimsl point goes in at the total number of counted places. e.g. 1.2 X 2.4 The number of decimal places in both multiples is '1' each, making a total of '2'. the multiplication of 12 X 24 = 288 . So the decimal point goes in at TWO(2) decimal places. . The correct answer is 2.88 . Similarly. 2.44 X 34.2 There are three ( 2 + 1 = 3) total places. Hence 244 X 342 = 83443 . So the decimal point goes in a the third(3) decimal place. ' 83.443 '. The answer!!!!! Casually, we can say 2 x 34 = 68 . So since there are decimal places as well, then the answer must be greater than '68', which is 83. The remaining numbers are the decimal places.
False. 2 x 0.55 = 1.1
0.03 X 0.42 Product means 'multiply'. To multiply decimals, first note that each number is to two decimal places, so the answer is to ( 2 + 2 = 4) decimal places. Multiply the numbers ignoring the decimal point. Hence 3 x 42 = 126 Then write '126' to four decimal places '0.0126'. The answer.
34.44 = 2 x 17.22 or 4 x 8.61, so the answer would appear to be two places.

Ex: 52.73 x 384.12 Round to 50 x 400 = 20,000 so when you do the actual math you know that there are 5 places to the left of the decimal.
If the two decimal numbers have x and y digits after the decimal points, then the product has (x + y) digits after the decimal point.
