The answer depends on what the decimal is.
For example, 4 * 3.5 = 14
But 4 * 3.6 = 14.4
The difference is that all whole numbers are decimal numbers, but not all decimal numbers are whole numbers. For example a whole number such as 1 is a decimal number but a decimal number such as 1.5 is not a whole number.
A decimal rational number can be expressed as a fraction A decimal irrational number can not be expressed as a fraction
Often, yes. But it depends on the numbers. For example, if you multiply 1.5 x 2, you get 3 as the answer (whole number). But if you multiply 1.5 x 3, you get a decimal of 4.5
you multiply by 2

The difference is that if you multiply with a whole number and then multiply with a decimal and you compare.You will notice the whole number is greater.You are very welcome.
A decimal point is the actual point. A decimal is the number that has a decimal point in it. For example; 28429.018

Often, yes. But it depends on the numbers. For example, if you multiply 1.5 x 2, you get 3 as the answer (whole number). But if you multiply 1.5 x 3, you get a decimal of 4.5
whenever you multiply a whole number by a decimal you get a decimal. 2.9x100=290
Three. Count number of zeros. If multiply decimal by 100 move decimal point 2 places, etc.
you multiply by 2
You usually get another number!
True
Whether a number is negative or positive makes no difference. In its full form, the cubed number will have three times as many digits after the decimal point. This assumes that none are lost through rounding.
