When "n" is any other number in the tenths place holder such as .1, .2, .3, ...., .8, .9 and no other digits in any other place holder.

The product of two whole numbers is always whole number?
Yes always
What is an expression so that the product of a whole number and a decimal is 0.28.?
4 x 0.07
When you multiply a whole number by 10 what is always true about the ones place in the product?
its always the same
What decimal tenths round to 6 to the nearest whole number the sum of the digits is divisible by 10 and their product is a perfect square what is the decimal?
5.5
Can the product of a whole number and a decimal number less than 1 ever be greater than the whole number?
Yes. -5 × 0.5 = -1 -1 is greater than -5.
When is the product of a decimal number n x 10 always a whole number?
When ' n ' has no more than one non-zero digit after the decimal point, and it is in the first place after the point.
When you multiply a decimal by a whole number the number places in the product is the same as the number of decimal places in the decimal factor true or false?
True
The product of two whole numbers is always whole number?
Yes always
Is it True or false when you multiply a decimal by a whole number the whole number of decimal places in te product is the same as the number of decimal places in the decimal factors?
It is false.0.2 * 25 = 5, which has no decimal places.
Why is a decimal smaller than a whole number?
A decimal number is not always smaller than a whole number. This is a decimal number 2.45 The number on the left of the decimal point shows the whole numbers. The numbers on the right of the point shows the parts/fractions. This number is not a whole number .098 This number is a whole number 2.00 This number has whole numbers and parts/fractions of the whole 2.098
If you multiply a non zero whole number by a decimal less than one would the product be less than or greater than the whole number?
It depends on the signs of the two numbers.The answer is tricky when at least one number is negative because you have to remember that "less than" means "farther to the left on the number line" and NOT "greater in magnitude". E.g. -20 is less than -4 because -20 is farther to the left even though its magnitude (absolute value) is greater.There are four possible cases:Whole number and decimal are both positive: The product is less than the whole number. The decimal reduces the magnitude of the product, so the product is to the left of the whole number on the number line. E.g. 0.5 * 10 = 5, which is less than 10.Whole number positive, decimal negative. The product less than the whole number. A negative times a positive is ALWAYS negative, so regardless of its magnitude the product is to the left of the positive whole number on the number line. E.g. 15 * (-0.2) = -3 and -3 < 15Whole number negative, decimal negative. The product is greater than the whole number. The product is negative but like in Case 1, the magnitude of the product is smaller, so the product is to the right of the whole number on the number line. E.g. (-8) * 0.3 = -2.4 and -8 < -2.4Whole number negative, decimal negative. The product is greater than the whole number. A negative times a negative is positive, and ANY positive number is always greater than any negative number regardless of magnitude. E.g. (-0.25) * (-12) = +3 and -12 < +3
How do you multiply a whole number by a decimal in the hundreths?
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.
When multiplying a decimal by a whole number is the number of decimal places in the product the same as the number of decimal places in the decimal factor?
Not necessarily: for example, consider 0.5 * 4 = 2
When you multiply a decimal by a whole number is the number of decimal places in the product the same as the number of decimal places in the decimal factor?
This is not necessarily true. 2 x 0.55 = 1.1
Explain how to multiply a whole number by a decimal in the hundredths?
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.
How do you estimate the product of a decimal and a whole number?
The answer depends on what the decimal is: the processes for 9999.02 and 0.02 are very different.
Why do you add a decimal point in math with numbers?
To the left of a decimal point are whole numbers. On the right of a decimal point are parts of a whole number.
