("123456789" ) ̅ Here 43. ("123456789" ) ̅ is non terminating but repeating. So, it would be a rational number In a non- terminating , repeating expansion of ?/?, q will have factors other than 2 or 5.
43.123456789 is a rational number of the form p/q and q is of the form 2m × 5n and the prime factors of q will be either 2 or 5 or both, 43.
As, we observe that 0.12012001200012... is a non terminating, non repeating number, it's an irrational number.
As 43.123456789 is a terminating decimal, so it is a rational number.
Answer: it's a rational number. 2.134bar indicates non-terminating decimal form.

D) 3.141141114 is an irrational number because it has not terminating non repeating decimal expansion.
1/3 = 0.33333... is a recurring, non-terminating decimal.
For example, the decimal 0.333333…, which is equal to the fraction 1/3, is a non-terminating repeating decimal.
Students learn that a repeating decimal is a non-terminating (non-ending) decimal. For example, 0.3333... and 9.257257... are repeating decimals. To indicate that a decimal is repeating, a bar is drawn above the digit or group of digits that repeats.
NUMBER SYSTEMS Recall s = 0.10110111011110... from the previous section. Notice that it is non- terminating and non-recurring. Therefore, from the property above, it is irrational.
No, because integers cannot be negative. Q. Jeremy says that 5.676677666777... is a rational number because it is a decimal that goes on forever with a pattern.
(d) 0.4014001400014... is a non-terminating and non-recurring decimal and therefore is an irrational number.
Thus, 0.101100101010……. is an irrational number.
For example, take the number 0.33333... Even though this is often simplified as 0.33, the pattern of 3's after the decimal point repeat infinitely. This means that the number can be converted into the fraction 1/3, and is a rational number.
A repeating decimal is a decimal that does not terminate but keeps repeating the same pattern. For example, 0.123123123. . . is a repeating decimal; the “123” will repeat endlessly. Any repeating decimal is equal to a rational number.
Repeating Decimals vs Terminating Decimals
On the other hand, terminating decimals are those that have an end. For example, while 0.4444.....is a repeating decimal, 0.4 is a terminating decimal.
2/root 3 is irrational.
Therefore, irrational numbers, when written as decimal numbers, do not terminate, nor do they repeat. √2, √3, √5 are examples of irrational numbers.
Is 3.14 a terminating decimal? If 3.14 is defined as the number value of pi, then it is not a terminating decimal. But by itself, without any bars or periods after it, the decimal is a terminating decimal.
Which of the following decimal numbers are repeating and which are terminating: 0.25, 0.3, 0.1212 … and 0.123123 … ? Answer: the first two are terminating decimals. The 0.1212 … and the 0.123123 … are repeating decimals. There is no universally accepted notation for a repeating decimal.
It is a non-terminating repeating number.
The number \pi is irrational while 3.14159265 is a rational number. As an irrational number, the decimal expansion of \pi never repeats and 3.14159265 is the best approximation with 8 decimal places.
3.141141114 is an irrational number because it is a non-repeating and non-terminating decimal.
Because 3.141141114... is neither a repeating decimal nor a terminating decimal, it is an irrational number.
