Stacy has 16 flowers in total
She has 4 vases
This implies that each of the vase will contain 4 flowers each
To determine the number of flowers in each verse
Number of flowers = Total number of flowers / Total number of vases
Total flower = 16
Total number of vases = 4
Number of flowers = 16 / 4
Since 4 is a multiple of 16
Therefore, 16 / 4 = 4
The answer is 4 flowers
Stacy will put 4 flowers each in each vase
