Not necessarily: for example, consider 0.5 * 4 = 2
That is not necessarily the case.2.5*4.3 = 10.75 which is larger than either of the numbers being multiplied.
You do not need to align decimal points when multipylng. You multiply the two numbers ignoring the decimal point but ensuring that any trailins 0s are present. The number of digits after the decimal point in the answer is the sum of the number of digits after the decimal points in the two multiplicands.
This is because we count in tens so that the place value of a digit is ten times the place value of the digit to its right.
When you multiply a number by a decimal you are dividing.
It could mean reduce the value of a decimal - perhaps by subtracting something or multiplying by a number smaller than 1.
You only get a smaller decimal if you do 0. something because your multiplying it by 0! oust like with the whole numbers, if you times something by 0 it gets smaller. only with a decimal, there's are still numbers less than the 0 so it gets smaller and smaller until you have a total of 0!
Multiplying 6.7 and 5.5 is the same as multiplying 0.67 and 55, or 67 and 0.55.
For the same reason that you can multiply two proper fractions and get a smaller number than either of them. You are multiplying either decimal by a number that is smaller than 1. As a result you get an answer that is smaller than 1 times the first number.

It is not. When multiplying two whole numbers you need not be concerned about placing the decimal point in the answer.

There is almost no difference. The only difference is placing the decimal point.
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.
It moves the decimal point two places to the right.
