To simplest form of a fraction you find the lowest common factor, usually I use this trick: if both numbers are even I keep dividing by 2 to the numerator and denominator till I can't anymore
In this case:
6 divided by 2= 3
--- ---
8 divided by 2= 4
now I can't simplify an further because 3 isn't an even number, therefore its the simplest form
remember= my trick only works if both number are even, if not you'll have to find the lowest common factor and divide them by that
Note: Consider the below figure attached with this question.
Given:
The ordered pair(6,y) is on line AC.
To find:
The y of this ordered pair.
Solution:
From the below figure it is clear that endpoints of AC are A(-7,-4) and C(1,4). So, equation of AC is





Subtracting 4 from both sides, we get


Thus, the equation of line AC is
.
Put x=6 to find the y for the ordered pair (6,y).


Therefore, the value of y is 9.
The method that is not correct is brandon's method.
16.4 is the answer. How to get the answer and others like it is like this. The first number after the decimal is the tenth place signaled by this .1 (For the examples I will always put the "1" where the value I'm trying to show) the hundredth place is here .21, and the thousandth is here .321 , hope this helps.
