All righty guys, so for this one here, we're going to try to figure out which of these are rational and which of these are irrational.
00:08
Okay, so how about 17 over 6? let's start there.
00:10
Now, remember what rational means.
00:12
Rational numbers means that you can write it with a fraction.
00:15
You can write the number as a fraction of integers.
00:19
Remember integers are just positive -negative counting numbers.
00:22
So 17 over 6.
00:23
Well, that is a fraction of it.
00:24
That is a fraction of integers.
00:26
So that is rational.
00:27
So that is not it.
00:29
We'll have to try to find something else.
00:30
Okay, how about the next one? your point, 07, 077, 777.
00:38
Okay, so for this one, it's a little bit more complicated, but notice the pattern here, 07, 077, 07, 777.
00:45
Okay, so what that means is that we are getting a pattern.
00:50
If you get a decimal with a pattern, that means it is not irrational...
