A park district has 45 pine trees and 30 oak trees to be planted. They are separating the trees for different areas. They want e

Lady_Fox [76]

Answer:

greatest number of areas that can be created=5

Step-by-step explanation:

given data

Number of pine trees = 45

Number of oak trees = 30

solution

we want area have same number of both trees

so we get here greatest number of area

we find here greatest common factor of 45 and 30

so Prime factorization of 45 and 30 are

45 = 3 × 3 × 5

30 = 2 × 3 × 5

as here GCF = 5

so here greatest number of areas that can be created=5
