Which of the following is the greatest value?
A. 74÷95
B. 7/8
C. 0.72
D. 74%
To solve this problem, we need to have all options in fraction form.
74 
95 = 
7/8 = 3/8
0.72 = 72/100
74% = 74/100
Now, find the least common denominator of 95, 8, and 100. The least common denominator is 3800, which we multiply by each fraction as follows:
74/95*3800=2960
7/8*3800=3325
72/100*3800=2736
74/100*3800=2812
We can see that the fraction 7/8 is the greatest among the given options.
Therefore, the Correct Answer is B.

Q #3: A math teacher obtained the following scores from a class of 45 students. Which of the following is the best way to display the frequency of each day of the week? Test score 50-59 60-69 70-79 80-89 90-99 Number of students 10 4 9 20 2
A. Scatterplot
B. Pie graph
C. Line graph
D. Histogram
Answer Explanation
In order for the teacher to better visualize the test performance for his class, he needs to present the mark distribution in chart form. A better chart visualizer is the histogram, which will show the frequency of marks against range of test scores. A bar graph will not be used because the rectangles need to touch one another.
In a bar graph, the rectangles do not touch each other. Therefore, it will not be a good chart visualizer.
