Final answer:
Soo has 27 flowers to plant, with 3 flowers going into each pot. By dividing the total number of flowers by the number of flowers per pot, we find that Soo uses 9 flowerpots.
Step-by-step explanation:
The question presents a simple division scenario where Soo has a total of 27 flowers (18 pink and 9 yellow) and she plants 3 flowers in each flowerpot. To calculate the number of flowerpots used, we divide the total number of flowers by the number of flowers per pot:
Total flowers = 18 pink + 9 yellow = 27 flowers
Number of flowers per pot = 3
Therefore, the number of flowerpots = Total flowers ÷ Number of flowers per pot
Number of flowerpots = 27 ÷ 3 = 9 flowerpots.
Soo uses 9 flowerpots to plant her flowers. It is a straightforward calculation ideal for reinforcing students' basic division skills.
