When ' n ' has no more than one non-zero digit after the decimal point,
and it is in the first place after the point.
True
It is false.0.2 * 25 = 5, which has no decimal places.
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
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.

Yes always

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

Not necessarily: for example, consider 0.5 * 4 = 2
This is not necessarily true. 2 x 0.55 = 1.1

The answer depends on what the decimal is: the processes for 9999.02 and 0.02 are very different.
To the left of a decimal point are whole numbers. On the right of a decimal point are parts of a whole number.
