Question:
What is the common denominator of
in the complex fraction 
A) 
B) 
C) 
D) 
Answer:
Option D : 3 is the common denominator
Explanation:
It is given that the complex fraction 
We need to determine the common denominator of
from the complex fraction.
Let us consider the fraction 
To find the common denominator, let us take LCM.
Thus, rewriting the above fraction as,

The LCM can be determined by multiplying the denominators.
Thus, we get,

Thus, the common denominator is 3.
Hence, Option D is the correct answer.
if we divide 20 by 12, we get a quotient of 1, and a remainder of 8.

The slope of the line is 2. Why? Well, see below for an explanation!
The slope of a line is found by using the formula rise/run (rise over run). This means that by starting at the initial value of the y-intercept, 3, we would count how many units away we are from the next complete point. We do so by counting from left to right, and in this case, going up and then to the right. To get from the point (0, 3) to the point (1, 5), we would move two spaces vertically along the y-axis and one space horizontally along the x-axis. Because the slope of the line is found using the formula m = rise over run, the slope would be 2/1 because we went up 2 points and to the right one. When simplifying, we will find that 2 divided by 1 equals 2. Hence, our slope is 2.
Your final answer: The slope of the line is 2/1 or 2. If you need extra help, let me know and I will gladly assist you.
