Only 6 of the 75 is a park are at least 30 feet tall. what percent of the trees are under 30 feet tall

6 out of 75 trees are at least 30 feet tall, therefore 69 out of 75 trees (the rest that is) are under 30 feet tall, and to convert that to percentage we have:

69 out of 75 = 69/75 = 0.92 = 92/100 = 92 out of a hundred and that is

= 92%
