It's because decimals are really fractions and all numbers get smaller when you multiply them by fractions.

Why when multiplying two decimal numbers together you get a smaller number you multiplied?
That is not necessarily the case.2.5*4.3 = 10.75 which is larger than either of the numbers being multiplied.
What do prime numbers mean?
Numbers that cannot be broken down any smaller. 2 is made of 1 and 1, but 5 is prime because there are no real (or whole) numbers multiplied together that equal five.
What decimal numbers are less than 1.4?
There are infinitely many decimal numbers which are less than 1.4.For a start, 1, 0, -1, -2 ... are all decimal numbers which are less than 1.4 1.39, 1.399, 1.3999, 1.39999. ... are all smaller and you can have infinitely many 9s in that sequence of numbers.
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 are the two prime numbers that can be multiplied to get the answer 39?
39 is the product when the two prime numbers 3 and 13 are multiplied.
Why when multiplying two decimal numbers together you get a smaller number you multiplied?
That is not necessarily the case.2.5*4.3 = 10.75 which is larger than either of the numbers being multiplied.
Why can you multiply two decimal numbers together and get an answer less than either one of the numbers you multiplied?
For the same reason that you can multiply two proper fractions and get a smaller number than either of them. You are multiplying either decimal by a number that is smaller than 1. As a result you get an answer that is smaller than 1 times the first number.
Is it possible for the final product of two numbers to contain fewer decimal places than either of the numbers being multiplied Why or why not?
huh. not a formal proof, but intuition says no, since decimal places represent fractions, and multiplication of fractions leads to smaller numbers (or more less than one), leading to more decimal places.
When multiplying a decimal by a decimal why do you get a smaller decimal?
You only get a smaller decimal if you do 0. something because your multiplying it by 0! oust like with the whole numbers, if you times something by 0 it gets smaller. only with a decimal, there's are still numbers less than the 0 so it gets smaller and smaller until you have a total of 0!
How do you times a decimal number with a usaul number?
A decimal number is multiplied by a non-decimal number the same way any two numbers are multiplied together. The place value of the numbers being multiplied must be kept in mind though. So if 2x3=6, just as 2x30=60, 2x0.3 would be 0.6. For numbers with more than one digit, you would treat the multiplication the same way as for non decimal numbers.
What is the difference between multiplying and dividing?
when multiplying the numbers increase unless it is multiplied by a decimal, it will then decrease. when dividing the numbers are divided (splitted) therefor it decreases unless it is divided by a decimal, it will then increase. Decrease means 'gets smaller or less' Increase means 'getting bigger or more'
Is it true when multiplying decimal numbers you must line up the decimals in the two numbers being multiplied?
No, it is not true.
How do you divide with a decimal?
multiply the decimal numerals by the amounts of digit numbers to the right, multiplied by 100 to change the decimal numbers to natural numbers. ie 1.232/1.232=1.232*1000/1.2328*1000=1232/1232=1
What two numbers can be multiplied so the product is smaller then one of the factors?
One of the numbers must be less that 1
How do you calculate decimal range of temperature?
You record the temperatures as decimal numbers and subtract the smaller from the larger.
What is the last step for multiplying decimal numbers?
To multiply decimal numbers, the decimal point is ignored and the multiplication is done as though they were (large) integers. The last step is to put the decimal point into the answer by ensuring the same number of digits follow it as were following the decimal points in the numbers multiplied together; trailing zeros can be removed at this point.
Is 1.21 is the smallest decimal?
No, there is no smallest decimal number. Decimal numbers represent real numbers and between any two real numbers there are infinitely many other real numbers. So, there are infinitely many decimal numbers between 0 and your 1.21: each one will be smaller than 1.21
