Is 6.48 a rational number?

Answer 1

#6.48# is clearly rational

The numbers that can be expressed as a fraction, or as a ratio between two quantities, are known as rational numbers.

A rational number can be written as #a/b, "where " a and b " are integers, but " b!=0#

All integers, all vulgar fractions, and all terminating and recurring decimals are considered rational numbers.

Irrational numbers cannot be written as a fraction and are infinite, non-recurring decimals, for example. #pi, sqrt 10, sqrt 33, sqrt 88#
What about #6.48?#
It is a terminating decimal. (it ends) It can be written as #648/100#
It is the ratio: #162:25#
#6.48# is clearly rational

Answer 2

Yes, 6.48 is a rational number. Rational numbers are those that can be expressed as the quotient or fraction of two integers, where the denominator is not zero. Since 6.48 can be written as ( \frac{648}{100} ), where both the numerator and the denominator are integers and the denominator is not zero, it 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.
