Answer:
None of them are irrational.
Step-by-step explanation:
An Irrational Number is a real number that cannot be written as a simple fraction.
Therefore:
-4 can be written as -4/1
2/9 is already in fraction
8.26 can be written as 826/100
11 can be written as 11/1
None of them are irrational.
However numbers like are irrational as they can not be represented as fractions.
Answer:
The next number of the series 0, 1/3, 1/2, 3/5, and 2/3 is 5/7
Step-by-step explanation:
The given numbers are;
0, 1/3, 1/2, 3/5, and 2/3
The number sequence is formed adding to each (n - 1)th term to get the nth term number in the sequence, with the first term equal to 0, as follows;
For the 2nd term, the (n - 1)th term is 0, and n = 2, gives;
The
For the 3rd term, the (n - 1)th term is 1/3, and n = 3, gives;
For the 4th term, the (n - 1)th term is 1/2, and n = 4, gives;
For the 5th term, the (n - 1)th term is 3/5, and n = 5, gives;
For the next or 6th term, the (n - 1)th term is 2/3, and n = 6, gives;
The next number of the series 0, 1/3, 1/2, 3/5, and 2/3 = 5/7.
