The answer depends on what the decimal is: the processes for 9999.02 and 0.02 are very different.
Not necessarily: for example, consider 0.5 * 4 = 2
Not really.If you are competent in using the basic operations of arithmetic (+ - * /) and follow the riles as these apply to decimal numbers then the decimal point will be correctly placed and finding a whole number estimate will only mean additional calculations which serve no purpose. On the other hand, if you are not that competent then how can you be sure that the whole number estimate that you find is accurate?
You can't change a whole number to a decimal. A decimal and a whole number are both numbers. A decimal is just a number lower than a whole number, or a number in between two whole numbers.
It is simply the whole number written as the product of its prime factors.It is simply the whole number written as the product of its prime factors.It is simply the whole number written as the product of its prime factors.It is simply the whole number written as the product of its prime factors.
A multiple of a number is the product of that number and any whole number.
39 is a whole number as in not a fraction or decimal.
352.84/10
True
It is false.0.2 * 25 = 5, which has no decimal places.
Yes
round the fraction to the nearest whole number, then times the two whole number together
When multiplying a whole number by a decimal with two places, ignore the decimal point and multiply as if you were multiplying two whole numbers. After you get the answer, re-insert the decimal point so that the product has two decimal places.
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.
Not necessarily: for example, consider 0.5 * 4 = 2
This is not necessarily true. 2 x 0.55 = 1.1
When multiplying a whole number by a decimal with two places, ignore the decimal point and multiply as if you were multiplying two whole numbers. After you get the answer, re-insert the decimal point so that the product has two decimal places.
False. 2 x 0.55 = 1.1
