Is the decimal 0.27227222722227... a rational or irrational

irrational number

Step-by-step explanation:

An irrational number is a number that cannot be expressed as a fraction for any integers and. .Irrational numbers have decimal expansions that neither terminate nor become periodic. 

An Irrational Number is a real number that cannot be written as a simple fraction.

Irrational means not Rational

Irrational

Step-by-step explanation: Notice that the decimal in this problem does not terminate which means it does not end.

Therefore, in order to decide whether it is rational or irrational, we need to determine whether the decimal is a repeating decimal. A repeating decimal is a non-terminating (non-ending) decimal in which one or more of the digits repeats.

There is a pattern to the digits, 27, 227, 2227, 22227, and so on but they're not exactly the same in every group. So there is no way to put a bar over any group of numbers to indicate that this is a repeating decimal.

Therefore, ur decimal is non-terminating and non-repeating which means that is must be an irrational number.

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
