Question

Holly can make 3 necklaces with 6 diamonds if holly has 30 diamonds how many necklaces can she make

Answer 1

15 necklaces with 30 diamonds 3/6= 15/30

Answer 2

6 diamonds ÷ 3 necklaces = 2 diamonds per necklace

If she needs 2 diamonds per necklace, and she has 30 diamonds, then you will divide again.

30 diamonds ÷ 2 per necklace = 15 necklaces

Holly can make 15 necklaces.
