Pretend there are no decimal points, and multiply the numbers together. Then count over (from the right) the number of decimal points of the two numbers combined.
For example:
3.4 * 0.185 = 0.6290
34 * 185 = 6290. There is one number to the right of the decimal point in 3.4, and three to the right in 0.185. One plus three is four, so starting from 6290. you move over four places.

How do you multiply two-digit numbers in a decimal?
To multiply two digit decimal numbers, multiply the numbers as you would without the decimals. To put the decimal in the answer, count the number of decimal places in the two numbers and put the decimal in the answer that many places to the left. For example: 5.12 x 6.35 = 32.5120. If the numbers were 51.2 x 63.5, the answer would be 3251.20.
What is a multiplication problem in which the product has two Decimal places?

How do you make composite?
Multiply together two or more prime numbers.
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
