Up to this point, the only types of numbers you've seen have been rational numbers. You can write any rational number as a fraction. The prefix ir- means not. What do you think it means for a number to be irrational? Can you think of any numbers that are irrational? must be around 50 words.

Step-by-step explanation:
No.
Rational numbers are those that can be expressed as a ratio (fraction) of two integers; irrational numbers are those that can't be expressed that way.
There is no overlap between the two categories. If a number is rational, it is not irrational, and vice versa.
It's generally easy to prove that a number is rational; you find the fraction and show it. Proving that a number is irrational is harder, and usually requires a proof. For example, mathematicians worked for centuries before proving that pi (π) was an irrational number.
Both rational and irrational numbers, however, are real numbers.
