Question 1 of 5

Ratio and Proportion: 0.5:20 :: X:200

Correct Answer: A

Rationale: To solve this proportion problem, you need to set up the ratio 0.5/20 equal to X/200. Cross-multiply to solve for X, which gives you 0.5 � 200 = 20X. Simplifying this, you get 100 = 20X, and then by dividing both sides by 20, you find that X = 5. Therefore, the correct answer is A, X = 50.

Question 2 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 3 of 5

What is the result of dividing 18.104 by 0.002?

Correct Answer: A

Rationale: When dividing by a small decimal like 0.002, it's equivalent to multiplying by 500 (since 1 � 0.002 = 500). Thus, 18.104 � 500 = 9052. This process involves shifting the decimal point three places to the right to calculate the answer.

Question 4 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 5 of 5

Ratio and Proportion 15:1000::x:100 = ?

Correct Answer: C

Rationale: To solve this proportion, set up the equation: 15/1000 = x/100. Cross multiply to get 15 * 100 = 1000 * x. Simplifying gives x = 1. Therefore, the correct answer is 1. The ratio 15:1000 is equivalent to the ratio 1:67. By setting up the proportion, we find that x = 1, making Option C the correct answer. This question assesses your understanding of ratios and proportions. Remember, when solving proportions, cross multiplication is a useful method to find the unknown value. In this case, the proportion is between 15 and 1000 in the first set, and x and 100 in the second set. By applying the cross multiplication method, you can determine that x equals 1, making Option C the correct answer.
