How is multiplying two decimals similar from multiplying one decimal by a whole number?
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
When multipling decimals why does the decimal move one place to the right?
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.
Why is the product of two decimals each less than one be less than one?
because you multiplying by 9
Why does the answer get smaller when multiplying decimals less than 1?
When multiplying decimals less than 1, the answer gets smaller because each decimal is less than 1. Multiplying a number by a value less than 1 will always result in a smaller product. Think of it as taking a fraction or a portion of the number, which will inevitably make the product smaller.
What are the facts about decimals in the eighths family?
The decimals increase incrementally by 0.125 for each eighth added. So 0 eighths is 0, 1 eighth is 0.125, 2 eighths is 0.25, etc.
How do you calculate 1.82 x 1.82?
1- Count the number of digits after each decimal.Ans: 42- Don't consider decimals when multiplying and multiply the numbers.Ans: 182 x 182 = 331243- Now, from right side we put decimal after 4 digitsAns: 3.3124
How do you multiply a mixed decimals?
Multiplying mixed decimals is almost just like multiplying whole numbers.For example:5.21 * 1.1You multiply these two numbers as if they didn't have decimal points, and you get 5,731; however, don't forget that you have decimals!Count the total number of digits after the decimal in each factor. You should get 3 since 5.21 has two digits after the decimal, and 1.1 has one digit after the decimal. 2 + 1 = 3Since you have 3 for that total, take the product (which is 5,731) and move the decimal point of that 3 spaces to the left.Your final product is 5.731:]

How to use significant digits in multiplication?
When multiplying numbers with different numbers of significant digits, the result should have the same number of significant digits as the least precise measurement. Count the number of significant digits in each number, perform the multiplication as usual, and then round the result to the least number of significant digits used in the calculation.
Why does the answer get smaller when multiplying decimals less than 1?
When multiplying decimals less than 1, the answer gets smaller because each decimal is less than 1. Multiplying a number by a value less than 1 will always result in a smaller product. Think of it as taking a fraction or a portion of the number, which will inevitably make the product smaller.
What do you do with the decimal point when multiplying?
When you multiply decimals first you should take away the decimals and just leave the number. Then multiply the two numbers together and you get a larger number than the two numbers you have. Then you have to count out how many decimals places you orignally had in both of the numbers then you put how every many decimal place in the first two numbers in the answer. Let me show you an example 34.56 x 76.096 Take away the decimals 3456 x 76096 Find the answer to this 262987776 Now go back to your two original numbers and find how many decimals places they each have 34.56 has 2 decimals 76.096 has 3 decimals Since you have 2 and 3 decimals you have to put 5 decimal places in your final answer 2629.87776 this is your answer
How many significant figures are in 3.4 times 17.05?
Count the significant digits in each of the factors, and take the smallest of them.

What is the definition of multiplying decimals?
It is defined as the process of finding the product of two numbers, in each of which the place value of any digit is ten times the place value of the digit to its right.
What is 2.5 x 2.5?
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.
