round up
A decimal number is one way of representing numbers where each place for a digit has a place value that is ten times that of the place to its right. Most all the numbers that you familiar with (judging from your question) will be decimal numbers. A decimal number need not be a [decimal] fraction.
Almost all numbers that we use in daily life are decimal numbers. The place value of each digit is ten times the place value of the digit to its right. And that is all that is required of decimal numbers. A decimal point is not necessary.
You align their decimal points. Sum the numbers as normal and, in the answer, place the decimal point so that it lines up with those of the summands.
explain why it is important to line up decimal numbers by their place value when you add or subtract them
These are the steps to convert a decimal into a fraction: (1) Place a 1 under the decimal to convert it to fraction form: .845/1 (2) Remove the decimal and place as many 0's to the right of the 1 as there are numbers to the right of the decimal: 845/1000 (3) Reduce the fraction to its lowest term: 169/200

Super Duper computers have calculated 'pi' to at least 50 billion places and still going.
9 and 3 are in the 14th and th decimal place for the value of pi.
three decimal places means three numbers after the decimal place, so 3.030
They are not integers or whole numbers. Typically irrational numbers are unending and do not repeat beyond the decimal place.
Multiply the numbers, count the total number of decimal places in the problem and place that many in your product.
use .25 as an example: 1) Place the decimal number over 1 in fraction form: .25/1 2) Remove the decimal and place as many zeroes to the right of the 1 as there are numbers to the right of the decimal mark: change .25/1 to 25/100 3) Reduce the fraction to its lowest term: 25/100 = 1/4
