the whole reason is this: multiplication is adding to that number in groups and division is subtracting from a number in groups.
For the specific case of whole numbers, you can consider multiplication to be repeated addition; and division to be repeated subtraction (see how often you can subtract something).
Decimal products are numbers that are the result of multiplication procedures and are not whole numbers. Decimal quotients are numbers that are the result of division procedures and are not whole numbers.
They are all numbers and obey the same rules for addition, subtraction, multiplication, division, exponentiation etc.
When it tells you to divide by a certain decimal it really will return an answer bigger than the number you started with because it is like multiplication.

You are working with numbers. One is a whole number and the other is a fraction of a whole number (with a decimal point, etc). You apply the same principles of subtracting one number from another or a fraction of one number from a fraction of another. Numbers is numbers!

Yes.
If you can never, by multiplying two whole numbers, get anything but another whole number back as your answer, then, YES, the set of whole numbers must be closed under multiplication.
The fundamental operations on whole numbers and decimals are addition, subtraction, division, and multiplication. However, multiplying and dividing decimals is a bit more complicated because you have to count decimal points to get an accurate answer.
Multiplication and division are mathematical operations. They are inverses, which means that they are opposites, so multiplying and dividing a number by the same constant yields the original number.Often multiplication is taught as taught as repeated addition- 7 multiplied by three is adding 3 sevens together. Although this works to compute positive whole numbers, it is not the mathematical definition. Mathematically, multiplication is the act of scaling numbers together.Division is the inverse of scaling numbers together. To visualize division, imagine a large object being divided into small, equal pieces.
same ---> answer is positivedifferent ---> answer is negativeBy the way, the two original numbers don't have to be integers. They can be anything ...whole numbers, decimals, mixed numbers, proper or improper fractions, irrationalnumbers, transcendentals, algebraic letters or symbols, numbers in scientific form,logarithms, mambo rhythms, you name it. Those two simple rules are always truefor multiplication and division.
