Answer:
rational numbers - 5.01212121212..., -5/250, √400
irrational numbers - √1000, ∛30, 0.01562138411...
Explanation:
rational numbers are any numbers that can be expressed as a ratio. whole numbers and integers are also counted as rational numbers.
5.01212121212... is a recurring number, which means that it can be written as a fraction. therefore, it is a rational number.
√1000 cannot be expressed as a fraction, which makes it an irrational number.
∛30 cannot be expressed as a fraction, so it is irrational.
-5/250 is a fraction, making it a rational number.
0.01562138411..., also cannot be expressed as a fraction since it is a non-terminating number. it is irrational.
√400 = 20, which is a whole number, thus it is rational.
i hope this helps! :D feel free to comment if you need to ask me anything.
