Ratio and Proportion: 0.6:X = 0.3:2 (Enter numeric value only.)

  • A. 2
  • B. 4
  • C. 3
  • D. 5
Correct Answer: B

Rationale: To find the value of X, we set up a proportion: 0.6/X = 0.3/2. Cross multiply to get 0.6*2 = 0.3*X. Simplify to get 1.2 = 0.3*X. Divide both sides by 0.3 to solve for X, which gives X = 4. Choice B (4) is correct. Choices A, C, and D are incorrect as they do not match the calculated value of X when solving the proportion equation.

Divide: 1 1/2 divided by 2 =

  • A. 0.75
  • B. 1
  • C. 1.33
  • D. 0.5
Correct Answer: A

Rationale: To divide 1 1/2 by 2, first convert 1 1/2 to an improper fraction: 3/2. Now, divide 3/2 by 2: 3/2 ÷ 2 = 3/2 x 1/2 = 3/4 = 0.75. Therefore, the correct answer is A (0.75). Choice B (1) is incorrect as the result is less than 1. Choice C (1.33) is incorrect as it is greater than 1. Choice D (0.5) is incorrect as it is the result of dividing 2 by 4, not 1 1/2 by 2.

In a class of 25 students, 44% are boys. How many boys are there?
