Q #1: Which of the following is the decimal equivalent of 3/8?

A. 375

B. 3.75

C. 37.5

D. 0.375

Answer Explanation
Q #2: (frac{[2 (8 + 2 * 6)]}{(16 div 2)} = frac{40}{8} = 5) Simplify the expression above. Which of the following is correct?

A. 6

B. 2

C. 5

D. 3

Answer Explanation

We follow the order of operations to solve the given expression.

First, we start with the numerator and solve

[2(8+2*6)]

We start with multiplication in inner brackets, 2*6=12. The expression becomes

[2(8+12)]

Then, we conduct the addition of 8+12=20. Then, the expression yields

[2(20)] = 2*20 = 40

Now, we solve for denominator, which is 16/2=8.

Thus, the expression is reduced into

(frac{[2 (8 + 2 * 6)]}{(16 div 2)} = frac{40}{8} = 5)

The expression reduces into 5.
Q #3: -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.
