Which of the following fraction groupings appears in descending order?
Show answer Hide answer
Answer: C. 9/13, 6/11, 8/15
Explanation
Converting the fraction nine over thirteen into a decimal yields approximately zero point six hundred ninety two. Converting the fraction six over eleven into a decimal yields approximately zero point five hundred forty five. Converting the fraction eight over fifteen into a decimal yields approximately zero point five hundred thirty three. Fractions can be compared directly by converting them into equivalent decimal number representations. Descending order requires arranging numbers from the largest numerical value down to the smallest value. Decimal comparison relies on evaluating digits from the tenths place moving rightward.
Financial analysts convert various fractional holdings into decimals to rank asset performance accurately. Engineering blueprints often require comparing fractional measurements to ensure correct hierarchical sizing. Culinary scaling frequently involves ordering fractional cup measurements for recipe adjustments. Option A places the smallest fraction first, which represents an ascending rather than descending sequence. Option B places the middle fraction incorrectly ahead of the larger fraction in the sequence. Option D starts with the middle fraction and fails to maintain a proper descending numerical order.
