Yes, 2/6 is a rational number. A rational number is defined as any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.
In this case, the fraction 2/6 can also be simplified. When we reduce 2/6 by dividing both the numerator and the denominator by their greatest common divisor, which is 2, we get:
2 ÷ 2 = 1
and
6 ÷ 2 = 3
Thus, 2/6 simplifies to 1/3, which is also a rational number. The key takeaway is that any fraction where both the top and bottom numbers are integers (and the bottom number is not zero) qualifies as a rational number.
