At the dinosaur rescue center, Dr. Dino prepared fossil-shaped feeding trays divided into 10 equal sections. Emek and Luna checked each tray before feeding the young dinosaurs. One small hatchling needed 3/10 of a tray, while a larger hatchling needed 7/10 of a tray. They counted the equal sections carefully and served the correct portions. Every young dinosaur received the right amount of food, and Dr. Dino smiled as the happy hatchlings finished their meals.

Hint
The bottom number shows the total equal sections, and the top number shows the sections eaten.
A feeding tray was divided into 10 equal sections. A hatchling ate 7 sections. Which fraction shows the amount of food the hatchling received?
3/105/107/1010/7Correct! The hatchling received 7 sections out of 10, which is 7/10.
Remember to count the sections received out of the total 10 equal sections.
Next🎉 Congrats! You got this question!
Hint
Add the number of sections eaten by both hatchlings.
A tray has 10 equal sections. A small hatchling eats 3/10 and a larger hatchling eats 7/10. How many sections of the tray are eaten altogether?
Correct! 3 sections plus 7 sections equals all 10 sections.
Add the sections eaten by both hatchlings: 3 and 7.
Next🎉 Congrats! You got this question!
Hint
Compare the number of sections taken from the same 10-section tray.
Emek says that 3/10 is larger than 7/10 because 3 is a smaller number than 7. Is Emek correct?
Yes, because smaller numbers always make larger fractionsYes, because 3/10 has fewer sectionsNo, because 7/10 has more equal sections of the trayNo, because fractions cannot be comparedCorrect! 7/10 is larger because it represents 7 sections, which is more than 3 sections.
When fractions have the same denominator, compare the top numbers to see which is larger.
