To Justify:The first step is to find the least common denominator of 3, 9, and 15.
Explanation of Solution
Given:
As per Cooper, the least common denominator of 3, 9, and 15 is 3 because 3 divides into all these number evenly.
But, 3 isnot least common denominators while 3 is highest common denominator.
As per Yu, the least common denominator of 3, 9, and 15 is 90 because you can divides 90 by all of those numbers without getting a remainder.
But,90are not least common denominators while 45 is least common denominator.
Now, factories the denominator 3, 9, and 15, we get
Least common denominator
Highest common denominators
Addition of the unlike fraction can easy, after find the least common denominator.
