Answer 1

`\huge\boxed{Hello~there!}`

First, let's add 213 and 33:

`\bf{213+33`

Add:

`\bf{246`

Now, is 246 rational or irrational?

Tip:

Irrational numbers have an infinite number of digits after their decimal point.

Example: 3.333333333... is an irrational number, because the 3's go on for ever.

Now, is 246 rational or irrational?

It doesn't have an infinite number of digits after its decimal point.

Thus, it's rational.

Answer 2

rational

Explanation:

213 +33=246

A quick way to check this is to see if 246 is a perfect square. If it is, then it is a rational number. If it's not a perfect square then it's an irrational number. We already know if 246 is a perfect square so we also can see that √246 is an irrational number.

246 is a rational number because it can be expressed as the quotient of two integers: 246 ÷ 1.
