When you multiply decimals, you just ignore the decimal until the end, then, to find the amount of decimal places in your answer, you add the amount of decimal places in both your factors
The product will have at most 2 decimal places.
If two decimal number have X and Y decimal places, respectively, then the raw product (before removing any trailing zeros) of the two numbers will have (X + Y) decimal places.
It depends on what numbers you are multiplying and how many decimals places they each have. It doesn't always haveto move to the right.
Two places.
The number of decimal places for the product will be the summation of the amount of decimal places of the 2 factors. For example, if your products have 2 decimals each to the right of zero then the product will have an answer with 4 decimals to the right of zero.
Multiplying decimals: Example: 2.5 x 1.3 = 3.25 Start by removing the decimal points, thus: 25 x 13 = (the answer is 325) Both 2.5 and 1.3 have 1 decimal places, so 1 + 1 = 2 (decimal places) Counting 2 places, right to left, places the decimal point here: 3.25 Search Google for division of decimals - there are plenty of how to examples and help on the internet!

Two of them.
The product will have at most 2 decimal places.
If two decimal number have X and Y decimal places, respectively, then the raw product (before removing any trailing zeros) of the two numbers will have (X + Y) decimal places.

Two places.
A simple trick with multiplying decimal numbers is to remove the decimals, multiply the two numbers, then add the decimals back in. The number of decimals you add back in is the total number of decimal places. For example, the stated problem has 1 decimal places in 2.1 and 2 decimal places in 5.01. So first we do the following: 21x501=10521 Now we add 1+2=3 decimal places into the result above: 10.521 That's the answer.
0.235 * 0.6891 = 0.1619385 What's to estimate? The total decimal places in the multiplicands is the total in the answer.
There are many ways to figure 2.5x2.5. If the decimals confuse you, remove the decimals and you may insert them at the end. 25x25=625.Remember*: When multiplying vertically, don't insert the decimal under the decimals in the factors:2.5 Instead, move the decimal two places to the left since therex2.5 are two decimals (one in each factor)____ so that the answer is 6.25.62.5 Not correct.
Multiplying by 100 is easier. Just move the decimal point two places to the right.
