Full solution

Q. Avi and Micah are teammates on a track and field team. Avi's best long jump is 1161\frac{1}{6} times as long as Micah's. Avi's best long jump is 3123\frac{1}{2} meters. How long is Micah's best long jump? meters\text{meters}
  1. Understand Relationship: Understand the relationship between Avi's and Micah's long jumps. Avi's best long jump is 1161 \frac{1}{6} times as long as Micah's. This means that to find Micah's best long jump, we need to divide Avi's best long jump by 1161 \frac{1}{6}.
  2. Convert to Improper Fractions: Convert the mixed numbers to improper fractions to make the division easier.\newline1161 \frac{1}{6} is the same as 76\frac{7}{6} when converted to an improper fraction.\newline3123 \frac{1}{2} is the same as 72\frac{7}{2} when converted to an improper fraction.
  3. Divide by Factor: Divide Avi's best long jump by the factor to find Micah's best long jump.\newlineWe need to divide 72\frac{7}{2} (Avi's long jump) by 76\frac{7}{6} (the factor).\newlineTo divide by a fraction, we multiply by its reciprocal.\newlineSo, we multiply 72\frac{7}{2} by 67\frac{6}{7}.
  4. Perform Multiplication: Perform the multiplication.\newline(\frac{7}{2}) \times (\frac{6}{7}) = (\frac{7 \times 6}{2 \times 7})\(\newline= \frac{42}{14}\newline= 3\)
  5. Convert to Mixed Number: Convert the result back to a mixed number if necessary.\newlineSince the result is a whole number, there is no need to convert it to a mixed number. Micah's best long jump is 33 meters.
