I would choose A. Samantha is testing the actual question "how many LIBRARY books are checked out by 7th graders at SAME time". She is still getting a result to the question, but an inaccurate reading as we do not know if ALL 7th graders are present in library and she is only doing a portion of 7th graders checking out books. However, Luis is going to cafe and some may never have gone to library or dislike reading tangible material. Basically both are bad surveyors, but Luis is definlately performing a more random approach.
Answer:
77
Step-by-step explanation:
b is present in both ratios, find first the LCM of 8 and 6, which is 24.
Multiply a:b=3:8 by 3 to get a:b=9:24
Similarly, multiply b:c=6:11 by 4 to get b:c=24:44
Then we conclude
a:b:c=9:24:44
Since there is no common factor among the three numbers, this is the simplest ratio possible.
If a,b and c are integers, the smallest values for a,b and c are 9,24,44.
Add up the three numbers to get the least value of a+b+c=77.
