Where do you find decimal numbers in real life?
A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. Since we normally count in tens, almost all the numbers that we come across are decimal numbers.
What decimal numbers come before zero?
The decimal numbers that come before zero are : -20.3, -40.8 , -0.6 , -6.02 and many more . These are the numbers come before zero and present on left side of the number line.
How can rounding come in handy?
Decimal numbers in calculations often display a spurious degree of accuracy. By removing these unnecessary digits, rounding can simplify mathematical operations without compromising the results.
What is the process of changing a fraction to a decimal or to a percentage?
The answer depends on the form of the fraction. If it is a decimal fraction, you need to nothing to convert it to a decimal! (?). If it is in the form of a rational fraction, you need to use long division to divide the numerator by the denominator. The division will either come to an end or will go into a repeating loop of digits. The quotient from the division is the decimal equivalent. To convert to a percentage, simply move the decimal point two places to the right - inserting os if required.
What decimal come between 12.6 and 12.61?
12.605
Where did the decimal point come from?
the decimal point came from the middle ages. before - was printed a man decided to place a point in between two numbers then decided to call it the decimal.
What is the square root of 194?
it is 13.92 and then a lot of numbers come after it but that is the first two digits that come after the decimal point

How many significant figures are in 0.074 kg?
There are 2. An easy trick is if there is a decimal point cross off all the 0s directly afte the decimal point until you come to a number that is not a 0. any number after that is significant. If there is not a decimal point come from the right side of the number and cross of all he 0s until you come to another number
Is it true that all decimal numbers rational numbers?
Short answer: yes.Irrational numbers like PI have what are called "decimal expansions." For PI, decimal expansions would be numbers like:3.143.141593.141592653589793238etc.These expansions are, themselves, rational numbers.The thing is, an irrational number has an infinitely long, non-repeating sequence of digits after the decimal point. While these digits can be computer forever to a precision limited only by how much effort a person is willing to put into it, they cannot be exactly represented as decimal numbers. Any possible finite decimal number that you come up with will not be a perfect representation of an irrational number.So strictly speaking, I would say that a decimal number can only ever represent a rational number.
Why isn't decimal numbers aligned when multiplying decimals?
When multiplying decimals, the decimal points are not only not aligned they are completely removed from the numbers to leave a multiplication of whole numbers which is done. Then the decimal point is put back into the answer by counting how many digits in total were after the decimal points in the original numbers and making the answer have the same number of digits after the decimal point. Example: 1.23 x 45.6 → 123 x 456 = 56088 1.23 has 2 digits after the decimal point, 45.6 has 1 digit after the decimal point making a total of 2 + 1 = 3 digits after the decimal point in the question, so there must be 3 digits after the decimal point in the answer → 1.23 x 45.6 = 56.088 Second example: 1.25 x 3.4 → 125 x 34 = 4250 2 digits + 1 digit = 3 digits in total in question must be after decimal point in answer: → 1.25 x 3.4 = 4.250 but normally any zeros that come at the end of a number after a decimal point are not written, so this would normally be written as: 1.25 x 3.4 = 4.25 A decimal number is a whole number divided by a power of 10, that is 10, 100, 1000, etc. This means that a decimal number can be written as an improper fraction with a power of 10 as the bottom number. So for the first example: 1.23 = 123/100 45.6 = 456/10 Multiplying the decimals together is the same as multiplying the two fractions together, which is done by multiplying the top numbers together and multiplying the bottom numbers together: 1.23 x 45.6 = 123/100 x 456/10 = (123 x 456)/(100 x 10) = 56088/1000 = 56.088
Which number of the below Dewey decimal classification come first?
I'm unable to see the list of Dewey decimal classification numbers you are referring to. Can you please provide the numbers so I can assist you?
What do you call the numbers in an adding problem?
you call them problems because you need to figure it out and it could come in your life and you have to figure it out
is greater 0.907 or 0.92755?
Think about it as moving the decimal point to the right until you come to a digit that is different in the two numbers. In this case it becomes 90 and 92 so 0.92755 is larger because 92 is larger than 90
What decimal come between 2.37 and 2.38?
There are infinitely many decimals between any two given (different) numbers. If you want the number exactly in the middle, take the average of the two numbers.
What does the math word trailing zero mean?
My Chemistry teacher defined trailing zero's as the ones that follow another number. We used them in relation to significant figures. If that's how you're using them (as significant figures) then the numbers are sometimes significant. If they come after a decimal point they're significant. Like 300.0 the 2 zero's before the decimal point are unsignificant, and the one after is (It's also a trailing zero).
