Answer 1

Answer:

25, 2, & 3 are rational numbers

π is a irrational number.

Explanation:

I think we need to find out the irrational number.

Here we learn main difference between rational and irrational number.

Rational Number:

All numbers whose written in fraction form where numerator and denominator are whole number.

All the whole numbers are rational number.

For example: 2 (because we can write 2 as $\frac{2}{1}$), $\frac{5}{6}$ etc

0.666666.... (endless repeating digits)

In given question: 25, 2 and 3 are rational numbers

Irrational Numbers:

All numbers that are not rational are considered irrational. An irrational number can be written as a decimal form, but not as a fraction form.

An irrational number has endless non-repeating digits to the right of the decimal point.

π = 3.141592...... (endless non repeating digits)

√2 =1.414213... (endless non repeating digits)

Answer 2

25, 2, and 3 are rational.
$\pi$ is irrational.
