Is -0.3 a rational number? is 3.14144144414444... a rational number?
1 answer:
I will try to make this as simple as possible.
First off, we need to know what a rational number is: A rational number is any number that can be made by dividing 2 integers. For example:
1.5 would be a rational number because 1.5 = 3/2 (3 and 2 are both integers)
With that being said, let's begin.
First off, let's start with -0.3, let's ask ourselves, can we make this number by dividing 2 integers, the answer is yes, we can, by doing we have the equivalent of -0.3, so now we know it's a rational number.
As for the second one, it can't be a rational number because it can't be made by dividing to integers, so the answer is:
-0.3 is a rational number, but 3.14144144414444 is not.

Step-by-step explanation:
Let's see how well I can explain this. is the same as a 30 degree angle which is in quadrant 1. If you picture the unit circle, right in the center of it is the origin. If you draw a straight line from 30 degrees and through the center (the origin), you will automatically "connect" with the reference angle of 30 (this is true for ALL angles on the unit circle). This puts us in quadrant 3. In quadrant 3, x is negative and so is y. So the terminal point of the reference angle for 30 degrees has the same exact values, but both of them are negative (again, because both x and y are negative in quadrant 3). I can't see your choices but the one you want looks like this:
