If 4 is x percent of 16, what is x?
  • A. 1/4
  • B. 4
  • C. 16
  • D. 25
Correct Answer & Rationale
Correct Answer: D

To find x, we start with the equation \(4 = \frac{x}{100} \times 16\). Rearranging this gives \(x = \frac{4 \times 100}{16}\), which simplifies to \(x = 25\). Option A (1/4) is incorrect as it does not represent a percentage of 16. Option B (4) misinterprets the relationship, as it does not reflect the percentage context. Option C (16) suggests that 4 is 16% of itself, which is also incorrect. Only option D (25) accurately represents that 4 is 25% of 16, confirming the correct calculation.

Which of the following is equivalent to 8,1/4?
  • A. 0.0825
  • B. 0.825
  • C. 8.25
  • D. 82.5
Correct Answer & Rationale
Correct Answer: c

To convert the mixed number 8 1/4 into an improper fraction, first multiply the whole number (8) by the denominator (4), resulting in 32. Then, add the numerator (1) to get 33, making the improper fraction 33/4. When you divide 33 by 4, you get 8.25. Option A (0.0825) is incorrect as it represents a much smaller value. Option B (0.825) is also incorrect, as it is less than 1. Option D (82.5) is incorrect, being ten times larger than the correct value. Thus, 8.25 accurately reflects the original mixed number.
What is the product of 2,2/3 and 3,3/8?
  • A. 5,5/11
  • B. 6,1/24
  • C. 7
  • D. 9
Correct Answer & Rationale
Correct Answer: D

To find the product of 2,2/3 and 3,3/8, first convert the mixed numbers to improper fractions. 2,2/3 becomes 8/3 and 3,3/8 becomes 27/8. Multiplying these fractions gives (8/3) * (27/8) = 216/24 = 9. Option A (5,5/11) and Option B (6,1/24) are incorrect as they do not represent the product of the two numbers. Option C (7) is also incorrect, as it is less than the calculated product. Thus, the only valid result from the multiplication is 9, confirming the correct answer.
Which of the following is equivalent to 1.04?
  • A. 52/51
  • B. 51/50
  • C. 27/25
  • D. 26/25
Correct Answer & Rationale
Correct Answer: D

To determine the equivalence to 1.04, we can convert each fraction to a decimal. Option A, 52/51, equals approximately 1.0196, which is less than 1.04. Option B, 51/50, equals 1.02, also less than 1.04. Option C, 27/25, equals 1.08, exceeding 1.04. Option D, 26/25, simplifies to 1.04, matching the target value exactly. Thus, only option D accurately represents 1.04, while the others deviate from this value.
1 is 3 percent of what number?
  • A. 1/3
  • B. 3
  • C. 30
  • D. 33,1/3
Correct Answer & Rationale
Correct Answer: D

To find the number of which 1 is 3 percent, set up the equation: 1 = 0.03 × x. Solving for x gives x = 1 / 0.03, which equals 33.33 (or 33 1/3). Option A (1/3) is incorrect as it represents a fraction far smaller than 1. Option B (3) fails because 3 percent of 3 is 0.09, not 1. Option C (30) is also incorrect; 3 percent of 30 equals 0.9. Thus, only option D (33 1/3) correctly satisfies the equation, making it the right choice.
