Several dinosaur hatchlings followed a feeding schedule in Dr. Dino's nursery. Emek and Luna checked each record to be sure every hatchling received the right amount of food. One hatchling had already eaten 4/10 of its daily meal and still needed 6/10. Another had eaten 7/10, so only 3/10 remained. Because all the portions used the same denominator, they easily added and subtracted the fractional parts. Their careful planning kept every hatchling healthy and fed on time.

Challenge 1 of 4
Hint
Compare the numerators because the denominators are the same.
Which hatchling had eaten more of its daily meal?
The hatchling that ate 4/10The hatchling that ate 7/10Both hatchlings ate the same amountThere is not enough informationCorrect! Since both fractions have denominator 10, 7/10 is greater than 4/10.
Try again. Compare 4 and 7 in the numerators.
Next🎉 Congrats! You got this question!
Hint
Subtract the numerator from 10 because the whole meal is 10/10.
A third hatchling had eaten 5/10 of its daily meal. What is the numerator of the fraction that still remains?
Correct! The hatchling still needs 5/10 of its meal.
Try again. Find what remains after eating 5/10.
Next🎉 Congrats! You got this question!
Hint
Add the part already eaten and the remaining part.
After the first hatchling finished the remaining 6/10 of its meal, what fraction of the daily meal had it eaten altogether?
9/1010/1011/1012/10Correct! 4/10 + 6/10 = 10/10, which is the whole meal.
Try again. Add the fractions with denominator 10.
