-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: Simplify the expression above. Which of the following is correct?

    A. 6

    B. 18

    C. 9

    D. 22

    Answer Explanation

    To simplify this expression, we follow the order of operations as follows:

    First, we start with the numerator and solve it as follows

    [2(6+3*9)]

    We start with multiplication in inner brackets, 3 * 9 = 27. The expression becomes

    [2(6+27)]

    Then, we carry out the addition of 6+27=33. Then, the expression yields

    [2(33)]=2*33=66

    Now, we solve for denominator, which is 6/2=3.

    Thus, the expression is reduced into

    The expression reduces into 22.
