Q #1: -1/3, -0.6, -1.5, -7/3. Of the numbers listed above, which number is the greatest?
A. -0.6
B. -7/3
C. -1/3
D. -1.5
Answer Explanation
To find the greatest value, we need to have uniform numbers. That is, all numbers must be in fraction for easy comparison. Therefore, we convert -0.6, and -1.5 into fractions as follows. For purposes of easy computation, we do not simplify the resulting fractions.
-0.6=-6/10
-1.5=-15/10
Now, the resulting fractions are -1/3, -6/10, -15/10, and -7/3. The greatest value is found by finding the LCM of the denominators and multiplying with each fraction. The LCM of 3 and 10 is 30. Then,
-1/3*30=-10
-6/10*30=-18
-15/10*30=-45
-7/3*30=-70
Based on the obtained values, -10 is the greatest value and -70 the least value. Therefore, -1/3 is the greatest of all the four options.

Q #2: A person weighed themselves at 120 lb. Three months later they weighed themselves at 160 lb. Which of the following is the percent of weight the person gained over 3 months? (Round to the nearest percent.)
A. 66%
B. 33%
C. 35%
D. 30%
Answer Explanation
We need to find the percent change in weight of a person. To find the percent change, follow the following steps:
- Find absolute change in weight
- Find relative change
- Find the percent change from relative change.
Absolute change is the difference between the final value and initial value. Our initial value is 120 lb and final value is 160 lb. Then,
Relative change is given by
Percent change is determined by
To the nearest whole number, the percent change is 33%.

Q #6: A pharmaceutical company’s stock price was $20.33 on Monday. On Tuesday, the price went up $0.35. On Wednesday, the price decreased from Tuesday’s price by $1.05. On Thursday, the price went up $0.95 from Wednesday’s price. Which of the following was the final price on Thursday?
A. $20.68
B. $19.63
C. $20.63
D. $20.58
Answer Explanation
Thursday’s stock price is found by determining the price of the stock on Tuesday and Wednesday.
Stock price on Monday= $20.33
Stock price on Tuesday= $(20.33+0.35)=$20.68
Stock price on Wednesday =$(20.68-1.05)=$19.63
Stock price on Thursday = $(19.63+0.95)=$20.58
Therefore, the price of the stock on Thursday was $20.58
