At the dinosaur dig camp, Emek and Luna found 24 small fossils ready for the visitor display. They wanted neat rows with the same number of fossils in each row. First, they tried 4 rows of 6 fossils. Then they tested 3 rows of 8 fossils. Both arrays used all 24 fossils, but the display case was too narrow for a row of 8. The 4-by-6 array fit perfectly. Emek checked that 4 times 6 equals 24, and Luna counted the fossils once more. They placed the finished display beside the dinosaur models, ready for the visitors.

Hint
Think about how many fossils must be in each of 4 equal rows to make 24.
Emek and Luna arranged all 24 fossils in 4 equal rows. Which multiplication equation shows how many fossils are in each row?
4 * 5 = 204 * 6 = 244 * 7 = 284 * 8 = 32Correct! Four rows with 6 fossils in each row use all 24 fossils.
Try again. Find the number that can be multiplied by 4 to make 24.
Next🎉 Congrats! You got this question!
Hint
Split 24 fossils equally among 3 rows.
The 3-row arrangement also used all 24 fossils. How many fossils were in each row?
Correct! There are 8 fossils in each of the 3 rows.
Try again. Find how many fossils go in each row when 24 fossils are divided equally into 3 rows.

Hint
Check which arrangement makes 24 fossils and has no more than 6 fossils in each row.
The display case can hold no more than 6 fossils in each row. Which arrangement uses all 24 fossils and fits the display case?
3 rows of 8 fossils2 rows of 12 fossils6 rows of 5 fossils4 rows of 6 fossilsCorrect! Four rows of 6 use all 24 fossils and fit the display case.
Try again. The arrangement must use exactly 24 fossils and have at most 6 fossils in each row.
