Is 6.8 a rational number?

Answer 1

Yes, #6.8# is indeed a rational number.

By definition, a rational number is a number that can be expressed by the ratio #a/b#, where #a# and #b# are integers and #b# doesn't equal #0#.
#6.8 = 68/10# and both 68 and 10 are integers.
In addition, #6.8# is a rational number (part of many other numbers) that make up real numbers (others including terminating decimals, repeating decimals, integers, and counting numbers, which are all rational numbers).

Among the instances are:

Counting Numbers: #" "0,1,2,3,4,...#
Integers: #" "...-3,-2,-1,0,1,2,3,....#
Rational Numbers: #" "7/9, 8.47, -5/8, 0.3...#
In conclusion, a number that doesn't meet these criteria would be otherwise considered an irrational number (a number that cannot be expressed in the form #a/b# e.g. #1.341823...#, #pi#, #sqrt(2)#, etc.).

Infinite, non-recurring decimals are known as irrational numbers.

Answer 2

Yes, 6.8 is a rational number. Rational numbers are numbers that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.

In the case of 6.8, it can be expressed as the fraction ( \frac{68}{10} ), where both the numerator (68) and the denominator (10) are integers. Therefore, 6.8 is a rational number.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
