Question 1 of 5
In the ratio 0.5 : 20 :: X : 200, what is X?
Correct Answer: B
Rationale: To find X, set up the proportion: (0.5/20) = (X/200). Cross multiply: 0.5 * 200 = 20 * X. Solve for X: 100 = 20X, so X = 100/20 = 5. Therefore, X is equal to 5 in the given ratio. The correct answer is B, as X equals 5 when the ratio is 0.5 : 20 :: X : 200.
Question 2 of 5
Sally eats 3/5 of her lunch. John eats 75%. Who ate more?
Correct Answer: A
Rationale: To compare the amount each person ate, we need to convert the fractions to percentages. Sally ate 3/5, which is equivalent to 60%. John ate 75%. By comparing 60% to 75%, we find that John ate more. Therefore, the correct answer is John, as he consumed a higher percentage of his lunch than Sally did.
Question 3 of 5
Which of the following decimals is the largest?
Correct Answer: D
Rationale: To determine the largest decimal among the options, you need to compare them by looking at the digits after the decimal point. When comparing 0.6, 0.667, 0.0688, and 0.68, consider that 0.6 is equivalent to 0.600, 0.667 remains 0.667, 0.0688 is already in its most precise form, and 0.68 is the same as 0.680. By comparing them, you can see that 0.68 is the largest decimal among the options provided. Remember, when comparing decimals, it's important to line up the decimal points to make accurate comparisons.
Question 4 of 5
Ratio and Proportion: 3: X = 5: 800. What is X? (Enter numeric value only.)
Correct Answer: A
Rationale: To find the value of X in the given ratio, set up the proportion: (3/X) = (5/800). Cross-multiply to solve for X: 3 � 800 = 5X. This simplifies to 2400 = 5X. Dividing both sides by 5 gives X = 2400/5 = 480. Therefore, the correct answer is A) 43.64.
Question 5 of 5
Ratio and Proportion: 3:5 :: X:10
Correct Answer: B
Rationale: To solve the proportion, set up (3/5) = (X/10). Cross-multiply to get 3 � 10 = 5X, leading to X = 6. This means that the correct choice is B, as X is equal to 6 to maintain the same ratio as 3:5 in the original proportion.
