holly can make 3 necklaces with 6 diamonds. if holly has 30 diamonds, how many necklaces can she make?

Answer 1

She can make 15 necklaces.

If Holly has 30 diamonds and she needs 6 to make 3 necklaces, you do 30 ÷ 6 = 5. You then take 5 × 3 to give you the amount of necklaces she can make, which is 15.

Answer 2

Holly can make 60 necklaces.
