Valentina made costume crowns for the king and the prince in her school play. She used 5 red gems and 8 purple gems for the king

kobusy [5.1K]

Answer:

The prince's crown had a greater ratio of red gems to purple gems.

Step-by-step explanation:

KING = 5 red / 8 purple

PRINCE = 4 red / 5 purple

Times the ratio for the king by 5

5(5) / 8(5) = 25/40

Times the ratio for the prince by 8

4(8) / 5(8) = 32/40

The prince has a greater ratio of red gems

Hope this is right, and sorry if it is incorrect. Have a good day!
