Answer:
√121 - rational
√2 - irrational
π - irrational
√50 - rational
1.3 - rational
3/7 - rational
0.27 - rational
Explanation:
A number is considered rational if it can be written as the ratio of two integers (i.e., a fraction), and it is considered irrational if it cannot be written as a ratio of two integers. In the given list, √121, √50, and 1.3 are all rational numbers because they can be written as fractions (√121 = 11/3, √50 = 5/2, and 1.3 = 13/10), while √2, π, and 0.27 are irrational numbers because they cannot be written as fractions. Note that 3/7 is also a rational number because it is a fraction with an integer numerator and an integer denominator.
