Respuesta :

Total number of trees in the park = 75
Number of trees that are at least 30 feet tall = 6
Then
Number of tress that are less than 30 feet tall = 75 - 6
                                                                          = 69
So
Percentage of trees that are less than 30 feet tall = (69/75) * 100
                                                                                = (69 * 4)/3
                                                                                 = 276/3
                                                                                 = 92 percent
So the percentage of trees that are below 30 feet is 92%. I hope the procedure is clear enough for you to understand.
Hi

75-6 = 69 trees

69/3 = 23
75/3 = 25

69/75 = 23/25 = 0,92 = 92% are under 30 feet tall
