What are two methods for determining the placement of the decimal point in the product?
When you multiply decimals, the decimal point is placed in the product.
When multiplying decimals the decimal points?
When multiplying decimals, the decimal points in the product are determined by the total number of decimal places in the factors being multiplied. Specifically, you count the total number of digits to the right of the decimal points in both numbers, and then place the decimal point in the product so that it has that same number of decimal places. For example, if you multiply 2.5 (one decimal place) by 0.4 (one decimal place), the result, 1.0, will have two decimal places.
How do you multiply 3 decimals?
To multiply three decimals, first convert each decimal into a fraction or ignore the decimal points temporarily. Multiply the numbers as if they are whole numbers, and then count the total number of decimal places in all three original decimals. Finally, place the decimal point in the product by moving it to the left by the total number of decimal places counted.
How do you know where to place the decimal point in long division with decimals?
In long division with decimals, you place the decimal point in the quotient directly above the decimal point in the dividend (the number being divided). If the divisor has a decimal, you can move the decimal point to the right until it becomes a whole number, and you must do the same with the dividend. After aligning the decimal points, proceed with the division as you would with whole numbers.
Which is the hundredths place in decimals?
Expressed as a decimal fraction, 0.01 is equal to one hundredth. The hundredths place is the second digit after the decimal point - the first is the tenths place.

When multiplying decimals how do you determine where to place the decimal in the answer?
If the two multiplicands have X and Y digits after the decimal place then their product (before removing any trailing 0s) has (X+Y) digits after the decimal point.

Where is the thousandth place in decimals?
It is the third digit after the decimal point.
Where is the tenths place in decimals?
It is the digit to the right of the decimal point. eg. 11.26. the 2 is in the tenths place
How do you know where to put the decimal when multiplying decimals?
If two decimal numbers have x and y digits after the decimal point respectively, then their product has (x + y) digits after the decimal point.

Must the product of 2 decimals be a decimal?
No. A decimal is a representation of a number such that the place value of any digit is ten times the place value of the digit to its right. It does not require a decimal point. So the decimal numbers, 3 and 4, can be multiplied together to give 1100 in binary.
What is the difference between multiplying decimals and multiplying whole numbers?
You do the multiplication in exactly the same way. The only extra thing is that when multiplying decimals, you need to place the decimal point (or decimal comma - depending on your country) in the correct position. If one number has, for example, 3 digits after the decimal point, and the other 4, you need to place the decimal point in the result (BEFORE eliminating unnecessary zeros) in such a way that there are, in this example, 7 digits (3 + 4) to the right of the decimal point.
Which is the hundredths place in decimals?
Expressed as a decimal fraction, 0.01 is equal to one hundredth. The hundredths place is the second digit after the decimal point - the first is the tenths place.
Is a decimal point a math symbol?
Possibly, as decimals can't be decimals without decimal points.
