At a dinosaur dig, Emek and Luna uncovered 48 small fossils. The museum sent 6 display trays, and each tray needed the same number of fossils. Emek first placed 5 fossils in each tray, using 30 fossils. That left 18. Luna shared the remaining 18 equally, adding 3 to each tray. Now every tray held 8 fossils. They checked that 6 groups of 8 made 48, then packed the balanced collection for transport.

Hint
Think about 48 divided into 6 equal groups.
The museum has 6 trays for 48 fossils. If the fossils are shared equally, how many fossils should go in each tray?
6 fossils7 fossils8 fossils9 fossilsCorrect! 48 fossils shared equally among 6 trays gives 8 fossils per tray.
Try again. Find the number that can go in each of 6 trays to use all 48 fossils.

Hint
Divide the 18 remaining fossils equally among the 6 trays.
After Emek put 5 fossils in each of the 6 trays, 18 fossils were left. If Luna shared those 18 fossils equally among the 6 trays, how many more fossils did she add to each tray?
Correct! Luna added 3 fossils to each tray.
Try again. Find 18 divided into 6 equal groups.
Next🎉 Congrats! You got this question!
Hint
Multiply the number of trays by the number of fossils in each tray.
Which calculation checks that 8 fossils in each of the 6 trays uses all 48 fossils?
48 - 8 = 406 + 8 = 1448 - 6 = 426 times 8 = 48Correct! 6 times 8 equals 48, so all the fossils are accounted for.
Try again. Use multiplication to check 6 equal groups of 8 fossils.
