Answer:
1. If 9 friends equally share a package of 85 craft sticks, each friend will receive 85/9 = <<85/9=9>>9 craft sticks. There will be 85 - (9 x 9) = 85 - 81 = <<85-81=4>>4 craft sticks left over.
2. 43 people are going to a concert, and 6 people fit in each car. They will need 43/6 = <<43/6=7>>7 cars.
3. Bess has 19 sunflowers and will put 4 sunflowers in each vase. She will need 19/4 = <<19/4=4>>4 vases.
4. For 38 + 3, the number of equal groups is 38/3 = <<38/3=12>>12 groups. The number left over is 38 - (3 x 12) = 38 - 36 = <<38-36=2>>2.
