Do you know the definition of a rational number?

sxdsouls:

no-

snowflake0531:

The easiest way to remember what it is, is that it is a number that either terminates(ends), or repeats Or, you could just say, a number that can be put into a fraction

sxdsouls:

okok-

snowflake0531:

So, looking at your choices, which ones can be put into a fraction/which ones terminate or repeat

sxdsouls:

I think B and E will end ?? idk

snowflake0531:

Huh B is a square root, if you search up square root of 50, it's a ton of random numbers

sxdsouls:

ah-

sxdsouls:

okokok

sxdsouls:

so B wont end c;

snowflake0531:

yep, B won't terminate or repeat, although yes, E is fraction

sxdsouls:

okok

snowflake0531:

Btw, the number one thing, when you get a list of random stuff of numbers Is to check those that are fractions, since fractions are most definitely rational numbers

sxdsouls:

ok

snowflake0531:

So, which ones are rational numbers

sxdsouls:

omg this is confusing wait- c´:

sxdsouls:

I give upp tytytyt c;

snowflake0531:

uhhh Wait a moment, let's go through each of them

snowflake0531:

For the first one, it shows ____ and then a ton of dots, this means that this just goes on and on. And since there's no line on top, it's not repeating, so, this is not a rational number

sxdsouls:

Ok makes sense

sxdsouls:

1 - rational 2 - 3 - 4 - 5 - I forgot

snowflake0531:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @snowflake0531 yep, B won't terminate or repeat, although yes, E is fraction \(\color{#0cbb34}{\text{End of Quote}}\)

snowflake0531:

We have so far that A and B are not rational numbers, but E is

sxdsouls:

OHH NOW I UNDERSTANDDDDDDDDDDDDDDDD

sxdsouls:

sorta

snowflake0531:

huh, okay lol Is c and d rational or irrational?

sxdsouls:
