At the dinosaur museum, Emek and Luna were preparing a new bone display. They needed to choose the most complete pieces from two sets. In the first set, pieces were marked 3/8, 5/8, and 7/8 of a whole bone. Luna compared the numerators and chose 7/8. In the second set, the pieces were 4/5, 4/7, and 4/9 of equal-sized bones. Emek knew that with the same numerator, fewer equal parts meant larger pieces, so he chose 4/5. Together, they checked their choices and placed the two largest pieces in the exhibit.

Hint
When the denominators are the same, compare the numerators.
In the first set of bone pieces, which fraction is greater than 3/8 but less than 7/8?
2/83/85/88/8Correct! 5/8 is greater than 3/8 and less than 7/8.
Try again. Since all these fractions have eighths, compare how many eighths each fraction has.
Next🎉 Congrats! You got this question!
Hint
The pieces have the same denominator, so find the difference between their numerators.
Luna compares the 3/8 and 7/8 bone pieces. How many more eighths of a whole bone is 7/8 than 3/8?
Correct! The 7/8 piece is 4 eighths larger than the 3/8 piece.
Try again. Find the difference between 7 eighths and 3 eighths.

Hint
When fractions have the same numerator, the fraction with the smaller denominator is greater.
Emek finds another bone piece marked 4/6. Where does it belong when the second set, 4/5, 4/7, and 4/9, is ordered from greatest to least?
Before 4/5Between 4/5 and 4/7Between 4/7 and 4/9After 4/9Correct! With the same numerator, 4/5 is greater than 4/6, and 4/6 is greater than 4/7.
Try again. Compare the denominators because all four fractions have the same numerator.
