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.
Not necessarily: for example, consider 0.5 * 4 = 2
This is not necessarily true. 2 x 0.55 = 1.1
False. 2 x 0.55 = 1.1
The product of 0.3 and 3 is 0.9. To calculate this, you simply multiply 0.3 by 3. When multiplying a decimal by a whole number, you can ignore the decimal point temporarily and multiply the numbers as if they were whole numbers. The final product will have the same number of decimal places as the total number of decimal places in the numbers being multiplied.
It is false.0.2 * 25 = 5, which has no decimal places.
Same as 3 * 74, just with decimal places.3 * 0.74= 2.22=====
When multiplying decimals, the decimal points in the product are determined by the total number of decimal places in the factors being multiplied. Specifically, you count the total number of digits to the right of the decimal points in both numbers, and then place the decimal point in the product so that it has that same number of decimal places. For example, if you multiply 2.5 (one decimal place) by 0.4 (one decimal place), the result, 1.0, will have two decimal places.
They will not have the same decision.
The one that says keep it in the same place.
