Q. Which inequality correctly orders the numbers 23,113 -\frac{2}{3},-\frac{11}{3} , and 2-2.55 ?\newlineChoose 11 answer:\newline(A) 23<113<2.5 -\frac{2}{3}<-\frac{11}{3}<-2.5 \newline(B) 2.5<113<23 -2.5<-\frac{11}{3}<-\frac{2}{3} \newline(C) 23<2.5<113 -\frac{2}{3}<-2.5<-\frac{11}{3} \newline(D) 113<2.5<23 -\frac{11}{3}<-2.5<-\frac{2}{3}
  1. Convert to common format: Convert all numbers to a common format to compare them easily. Since we have fractions and a decimal, let's convert 2.5-2.5 into a fraction. 2.5-2.5 is the same as 52-\frac{5}{2} or 212-2 \frac{1}{2}.
  2. Compare fractions: Compare the fractions by finding a common denominator or by converting them to decimals. The common denominator for 33 and 22 is 66. So, we convert 23-\frac{2}{3} to 46-\frac{4}{6} and 113-\frac{11}{3} to 226-\frac{22}{6}. We also convert 52-\frac{5}{2} to 156-\frac{15}{6} to compare with the other fractions.
  3. Compare with common denominator: Now that we have all numbers with a common denominator, we can compare them directly. We have 46-\frac{4}{6}, 226-\frac{22}{6}, and 156-\frac{15}{6}. It's clear that 226-\frac{22}{6} is the smallest, followed by 156-\frac{15}{6}, and then 46-\frac{4}{6} is the largest (since we are dealing with negative numbers, the larger the absolute value, the smaller the number).
  4. Translate back to original numbers: Translate the comparison back into the original numbers. 226-\frac{22}{6} corresponds to 113-\frac{11}{3}, 156-\frac{15}{6} corresponds to 2.5-2.5, and 46-\frac{4}{6} corresponds to 23-\frac{2}{3}. Therefore, the correct order is -\frac{11}{3} < -2.5 < -\frac{2}{3}.
  5. Match correct order: Match the correct order to the given answer choices. The correct order we found is option (D) \frac{-11}{3} < -2.5 < \frac{-2}{3}.
