Is 0.49 a rational or irrational number? Explain how you know.

Answer:
Rational
Step-by-step explanation:
Rational numbers are numbers that can be represented as fractions. This means that the number must have an ending point or repeat in some way. The number 0.49 repeating satisfies the second part of the definition. It can also be represented as the fraction, [tex]\frac{49}{99}[/tex]. So, it must be rational. An irrational number would never repeat and could not be written with the bar shorthand.
