-3/5, -0.9, -1.9, -8/3 Of the number listed above, which number is the greatest?

A. -3/5

B. -0.9

C. -1.9

D. -8/3

Answer Explanation:

To answer this question, we need to convert the numbers into a similar form. Converting decimal numbers into fraction is appropriate to finding the greatest number.

-0.9 becomes 9/10

-1.9 becomes 19/10

Now we find the LCM of the denominators of the four fractions. The LCM of 5, 10 and 3 is 30. Multiply each fraction with the LCM to compare the fractions.

-3/5*30=-18

-9/10*30=-27

-19/10*30=-57

-8/3*30=-24

The greatest number is -18, meaning -3/5 is the greatest number.

Therefore, the Correct Answer is A.

  • Q #1: There are 800 students enrolled in four allied health program at a local community college. The percent students in each program is displayed in the pie chart. Which of the following is the number of students enrolled in the dental hygiene program?

    A. 168

    B. 144

    C. 336

    D. 152

    Answer Explanation

    we are to use the pie chart to find the number of students enrolled in dental hygiene care.

    Letting x represent the number of students enrolled in dental hygiene care, we set the proportion equation with number of students as numerator and percentage as denominator. It should be noted that the whole pie chart represents 100% of the 800 students. Then,

    We solve the value of x by cross-products.

    Therefore, 144 students will enroll for a dental hygiene program.

  • Q #2: Which of the following is the total number of whole boxes that measure 2.5 ft * 2.5 ft * 2.5 ft that can be stored in a room that measures 12 ft * 12 ft * 12 ft, if the size of the boxes cannot be altered?

    A. 111

    B. 105

    C. 150

    D. 120

    Answer Explanation

    The number of boxes to fit the room is found as volume of the room divided by the volume of the box.

    Number of boxes:

    \(\frac{volume\ of\ the\ room}{volume\ of\ the\ box} = \frac{12ft\ *\\ 12ft\ *\ 12ft}{2.5ft\ *\ 2.5t\ *\ 2.5ft}\ =\ 110.592\)

    The approximate number of boxes that can be stored in the room is approximately 111 square feet.

  • Q #3: A recipe calls for 3.4 teaspoons of milk. 1 teaspoon equals approximately 5 mL. Which of the following is the correct amount of milk in mL?

    A. 16.8 mL

    B. 17.0 mL

    C. 10.5 mL

    D. 6.8 mL

    Answer Explanation

    we are asked to find the amount of milk in mL using the given information.

    If we let x represent the amount of milk in mL, we set up a proportion with number of teaspoons on the numerator and amount in mL in the denominator.

    A recipe of 3.4 teaspoons is equal to 17.0 mL.
