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