2.4 x 8.6
34.44 = 2 x 17.22 or 4 x 8.61, so the answer would appear to be two places.
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
If two decimal number have X and Y decimal places, respectively, then the raw product (before removing any trailing zeros) of the two numbers will have (X + Y) decimal places.
False. 2 x 0.55 = 1.1
2.4 x 8.6
34.44 = 2 x 17.22 or 4 x 8.61, so the answer would appear to be two places.
1). Multiply (3 x 42) = 1262). Mark off 4 decimal places: 0.0126
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.
