Multiply the first 3 prime numbers that are 2 3 and 5 so the answer would be 30
Think of it like this where X is amount of packs for strawnerry gum and y is blue berry gum. 9x=12y. if you get 4 packs of strawberry gum you get 36 pieces and if you get 3 packs of blueberry gum you get 36 pieces also. so you would do 9(4)=12(3). Hope I helped!
