You don't simplify rational numbers, but sometimes you can simplify a fraction.
The way to do that is to divide the top and bottom by their greatest common factor.
The greatest common factor of 57 and 69 is 3 . When you divide the top and
bottom by 3 , you have 19/23 . That's the simplest form of that particular fraction.
The answer would be 400$. This is because 40 x 10 = 400.
It’s pretty much where part of the number is repeated. For example, 0.0087878787 (87 is repeated) or 0.0567567567 (567 is repeated)
185 since it is going by ones, Hope that helped. :)
I think it’s y=-1x+ -8 or could be written as y=-1x-8
