Answer:
c) 0.23
Step-by-step explanation:
Let's look through these one by one to check if they're a rational number or not. First, we have e. It's also known as "Euler's number," and it goes on forever and doesn't repeat. Since it doesn't repeat or terminate, it's not a rational number.
What about [tex]\sqrt{3}[/tex]? Well, if we look this up, we get 1.732050... and it doesn't look like it repeats or terminates. So this isn't a rational number.
Let's take a look at 0.23. Well, this looks like a terminating decimal. It can be written as a fraction ([tex]\frac{23}{100}[/tex]). So it's a rational number.
Just to make sure, let's check [tex]\frac{\pi }{2}[/tex]. While it is written as a fraction, when you divide it out, it creates a non-repeating, non-terminating decimal, so this is not a rational number.
Hopefully that was helpful! If you have any more questions, let me know.
