Final answer:
Mrs. Oen can make 18 bouquets, with 2 of each flower in each bouquet.
Step-by-step explanation:
Mrs. Oen picked a total of 18 tulips and 20 daffodils. To divide them into bouquets with the same number of flowers, we need to find the greatest common divisor (GCD) of 18 and 20. The GCD of 18 and 20 is 2, meaning each bouquet will have 2 tulips and 2 daffodils. To calculate the number of bouquets, we divide the total number of flowers by the number of flowers in each bouquet. So, 18 bouquets can be made.
