Answer: 6
Step-by-step explanation:
Given : Tina is placing 30 roses and 42 tulips in vase for table decorations in her restaurant .
Each vase will hold the same number of flowers and each vase will have only one type of flower .
Then, the greatest number of flowers she can place it each vase will be the greatest common factor of 30 and 42.
Prime factorization of 30 and 42 :
[tex]30=2\times3\times5\\\\42=2\times3\times7[/tex]
We can see that greatest common factor of 30 and 42 = [tex]2\times3=6[/tex]
Hence, the greatest number of flowers she can place it each vase =6
