Is 12.2882057274 rational or irrational?
12.2882057274 is rational, but it is a rational approximation of an irrational number.Any number that can be expressed exactly as a fraction is rational, and that includes any number that, when written in decimal form, uses a finite number of digits.However, √151 (the square root of 151), which is approximately 12.2882057274445..., is an irrational number. You could keep getting a closer and closer approximation with more and more digits, but you would never hit it exactly, and you will never end up with a repeating series of digits.0.80428571428571428571428571... is also a rational number, because, after the 0.80 at the beginning, you have a repeating sequence of 428571. It's a decimal representation of 563/700.
Is 1.234567891011121314 a rational number?
Yes it is. Any number that you can write completely using digits, and a decimal point or a fraction bar if you need one, is rational. If the number you wrote in the question is all there is to it, and it doesn't keep going on forever, then it's rational.
What is one third approximately as a decimal?
0.3333... (keep going depending on how close an approximation you want).
What is the meaning of terminating decimal?
A terminating decimal is a number that stops dividing after a number of decimal points and is therefore a rational number.For instance, 1/2 = 0.5. (so 0.5 is a rational number because it can be written as a fraction).Terminating number or better known as terminating decimal has an end. It has to stop after the decimal point.Examples:1/2 = 0.51/4 = 0.25
What is 6 over 35 as a decimal?
0.1714285714285714285714 etc.. And although it does turn out to be like that, the proper way to right it without repeating is .....________ 0.1714285 Note: Please ignore the dots in front of the line. And the line is to be writing above the number starting with the 7, indicating that that's what repeats. Also keep in mind that just because that it's a repeating decimal doesn't mean it's irrational. It's written as a fraction. Any fraction is rational, so this repeating decimal is rational.
