Is a repeating decimal rational?
yes, repeating decimals (those that have infinite - never ending - number of digits after the decimal point and these decimals show repeating pattern) are rational numbers, because they can be written as fractions.
What is the name of the decimal that never stops?
The decimal that never stops is called recurring decimal. For example - 1/3 = 0.3333... and goes on. Such decimals are written with a dot or bar on top of the numbers which are repeating.
Does the difference between a positive decimal and a negative decimals can always sometimes or never be positive and why?
It is always positive, and not just for decimal numbers but for all numbers.
What is a never ending decimal called?
It is a non-terminating decimal.
Is pie a whole number?
No. Pie is commonly known as 3.14 however pie has a never ending sequence of numbers after the 4
What are some facts about Irrational numbers'?
Irrational numbers are numbers that can't be expressed as fractions and are never ending decimals that can't be expressed as fractions as for example the value of pi as in a circle.
What do you call never ending decimals?
It depends on whether they are never ending but recurrent or never ending but non-recurring. An example of the first is 2/11 = 0.1818.... where the 18s go on for ever. This is called a recurring decimal. An example of the second is the decimal representation of sqrt(2) = 1.41421356... which goes on forever, but which does not settle into a repeating pattern. These are called non-recurring decimals.
What is the largest number that rounds to 400 to the nearest hundred?
Of whole numbers only, it's 449. Of all numbers including decimals, it's 449.99999... with the 9s never ending.
Is a repeating decimal rational?
yes, repeating decimals (those that have infinite - never ending - number of digits after the decimal point and these decimals show repeating pattern) are rational numbers, because they can be written as fractions.
Will repeating decimals always or never be rational numbers?
They will always be rational numbers.
Is it true that every fraction can be written as a decimal?
Any fraction composed of real numbers can be written as a decimal approximation.However, some irrational numbers, like Pi, are never-ending as decimals, and must be rounded off.
Are repeating decimals sometimes always or never rational numbers?
always
What decimals are irrational?
Irrational numbers are real numbers which cannot be expressed as fractions. In other words, decimals that never repeat. Examples: sqrt(2) -pi 4*sqrt(3)
What is the name of the decimal that never stops?
The decimal that never stops is called recurring decimal. For example - 1/3 = 0.3333... and goes on. Such decimals are written with a dot or bar on top of the numbers which are repeating.
Are all decimals irrational numbers?
only decimals that never end and never repeat are irrational. a decimal is rational if it can be written as a fration or ratio of two numbers. for example: .3434343434343434... 100x=34.34343434... -x 99x=34 34/99
How is dividing decimals different than dividing whole numbers?
in dividing decimals you never get a remainder and in dividing whole numbers you do. +++ More to the point perhaps, you are working in powers of 10 all the time.
Is there a chart that converts decimals to inches?
No and there never will be. Decimals are a way to express number. They are not lengths, or mass, or volume or time or anything. Just pure unadulterated numbers. And numbers cannot be measured in inches!
