The seventh grade enrollment at Goddard, increased from 380 to 456 students. What is the percent of increase?

20%

Step-by-step explanation:

Calculate percentage change

from V1 = 380 to V2 = 456

(V2−V1)|V1|×100

=(456−380)|380|×100

=76380×100

=0.2×100

=20%change

=20%increase

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
