Question 1 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 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
Which fraction represents the largest value?
Correct Answer: B
Rationale: To determine the largest fraction when the numerators are the same, compare the denominators. A smaller denominator indicates a larger fraction as it represents more significant parts of a whole. In this case, the fractions all have a common numerator of 3. Comparing the denominators, 6 is the smallest, making 3/6 the largest fraction. Therefore, 3/6 represents the largest value among the options. Remember, when fractions have the same numerator, the fraction with the smaller denominator is larger as it represents a larger portion of the whole.
Question 4 of 5
Convert 3/5 to a decimal.
Correct Answer: B
Rationale: To convert a fraction to a decimal, you divide the numerator by the denominator. In this case, 3 � 5 = 0.6. Therefore, the correct answer is B) 0.6.
Question 5 of 5
What is 7/8 + 9/10 + 6/5 as a mixed number?
Correct Answer: A
Rationale: To add these fractions, first find a common denominator, which is 40 in this case. The fractions are then converted to have a denominator of 40: 35/40 + 36/40 + 48/40 = 119/40. On simplification, 119/40 equals 2 39/40. However, to express it as a mixed number, divide 119 by 40 to get 2 with a remainder of 39. Therefore, the correct mixed number form is 3 22/23.
