-- Ignore the decimal point; just multiply the two whole numbers. -- After the multiplication is done, put the decimal point back into the product. Put it in the right place so that the product has as many digits after the point as the original decimal had. If there aren't enough digits in the product to do that, add some zeros to the left end of it.

You don't move the decimal point at all. You just multiply the numbers and the point should sort itself out or be put of how many digits it is to be.

However many digits are after the decimals, that's how many times you move it to the left. For example: 1.38 x 9.24. When you get the product, you would move the decimal 4 places to the left because you have 4 digits after decimals. Hope this helps! (:

Ignore the decimal points and multiply the numbers to give the product: 308*29 = 8932Count the number of digits AFTER the decimal points in the two numbers. Two in the first and one in the second, making three in all.That is the number of digits after the decimal point that you want in the answer. So insert the decimal point that many digits from the end of the product.Thus 8932 becomes 8.932Done!

You simply multiply the two numbers together ignoring the decimal point. You then count the number of decimal places in each of the multiplicands and add them together. In the product, you put the decimal point so that there as many digits after the decimal point as that sum.For example, to multiply 2.63 by 3.271263 * 3271 = 860273.There are 2 digits after the decimal point in the first multiplicand and 3 in the second. 2 + 3 = 5So the decimal point in the answer is placed so that there are 5 digit after it: 8.60273

Billions are integers and so there will be no decimal points or digits after it.

The answer depends on how many decimal places are in the summands.

There are 27 of them.

You need to add up the number of digits to the right of the decimal to find the number of digits in the answer. If the first factor has 2 digits to the right of the decimal point and the second factor has 3, the final answer will have 5 digits to the right of the decimal point.

There can be only one.

It takes 7 digits.

A decimal is a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. It can have any number of digits: from one to infinitely many.
