Yes, 49 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, 49 can be written as
49/1. Both 49 (the numerator) and 1 (the denominator) are integers, and since the denominator is not zero, it meets the criteria for being a rational number.
Moreover, rational numbers can be whole numbers, fractions, or finite/repeating decimals. Since 49 is a whole number, it fits perfectly within the definition of rational numbers.
