Every number has factors. Some numbers share factors. To
simplify a fraction, divide the numerator and the denominator,
each separately, by the factors they share
in common. The only common factor, at the end, should be 1.
Here's an example:
![\frac{45 x^{2} }{9x} = \frac{5 x^{2} }{x} = 5](https://tex.z-dn.net/?f=%5Cfrac%7B45%20x%5E%7B2%7D%20%7D%7B9x%7D%20%3D%20%5Cfrac%7B5%20x%5E%7B2%7D%20%7D%7Bx%7D%20%3D%205)
I first divided by 9 and ten by x.
Answer:
Yes, the difference of two rational numbers is a rational number. The reason for this lies in the following facts: The product of two integers is an integer. The difference between two integers is an integer.
Step-by-step explanation:
For 645 and 738:
For these numbers we have that the difference between both is:
738 - 645 = 93
For 645 and 649:
For these numbers we have that the difference between both is:
649 - 645 = 4
Therefore, comparing the first two numbers of the second two numbers is different because the difference between the first two numbers is much larger.
Answer:
The difference between the first two numbers is much greater than the difference between the second two numbers.

Collinear is when two points are on the same plane. For example: in this picture A B C and D are collinear. Two points can still be collinear if they don’t have a line in between them too, just as long as you can draw a straight line between them they are collinear.
